Validate Your Design Inside Solid Edge

Solid Edge gives you world-class capabilities to design and build realistic 3D solid models representing the form of your parts. Solid Edge also allows you to create assemblies of the 3D solid parts in order to allow you to clearly understand whether the parts will properly together as an assembly.What Solid Edge will not do is provide you with the ability to know if your design will actually meet it’s intended (and sometimes unintended) performance criteria? To determine if a design will perform as expected, the physical assembly is produced and a series of costly lab or field tests are done. This testing usually produces several design changes and the process continues until all production performance criteria are met. The problem with this is that design validation is done too late in the process.

Don’t Wait to Validate!

Dynamic Designer allows you understand the true dynamic function of your design inside the Solid Edge environment before your produce or assemble physical hardware. Design Validation with Dynamic Designer allows you to build, test and refine the function of your CAD models and output the same performance information typically gathered physically (e.g. part interference, motor size, cam performance, gear and linkage layout, etc.). Using Dynamic Designer you will understand the mechanics of your design before you cut metal or mold plastic, all within the familiar Solid Edge environment. Design revisions are easier and less costly if motion problems are identified before you build and test a physical assembly. If you have questions about how a design works or performs, Dynamic Designer can help you.

The Products – Three Levels to Meet Your Needs and Budget

The Dynamic Designer product family consists of:

Motion Professional

Motion

Simply Motion

Motion Professional provides you with the complete motion validation functionality required to make sure your designs will work properly before you build them. Motion and Simply Motionare subsets of the Motion Professionalproduct and are used to understand substantial, but limited aspects of a mechanism motion. Simply Motion currently comes free with every copy of Solid Edge so if you already have Solid Edge, you already have Simply Motion.

Regardless of which product you choose, all Dynamic Designer products help you test the function of your mechanism before you build them. The process is simple. From your Solid Edge assembly, you will create a motion model containing constraints, contacts, forces, and actuators. You will then simulate mechanism motion using the most powerful simulation engine in the world: MSC.ADAMS. Finally, you will review animations, plot engineering data, and check for interferences. All seamlessly inside Solid Edge.

The Process – Four Easy Steps

Regardless of which product you choose, all Dynamic Designer products help you test the function of your mechanisms before you build them.

The process involves four simple steps:
- Creating the Motion Model
- Adding/Controlling Motion
- Running the Simulation
- Reviewing Results
Creating a Motion Model

Once a Solid Edge assembly is complete, mechanical joints are easily created, either by automatically converting them from your existing assembly constraints using Dynamic Designer’s Automatic Constraint Mapping, or by using the unique Intellimotion builder which walks you through the step-by-step model building process.

Adding/Controlling Motion

To make your simulation closely reflect real word functionality, Dynamic Designer allows you to add various motion characteristics to your model. Dynamic Designer supports motors, actuators, gravity, realistic contact between bodies, springs, friction, damping and other generated forces as needed.

Running the Simulation

Running a simulation is as simple as specifying how long you want the process to run and then clicking the calculator icon to compute your motion results.

Reviewing Results

Dynamic Designer calculates several types of results that you can use to verify the operation of your design. Moving interference animations, AVI and VRML files give you the visual feedback you need to understand if your design will work properly. However, what truly sets Dynamic Designer apart from a general animation package is the ability to provide accurate engineering data associated with the movement of the assembly. Result vectors and plots of displacement, velocity, acceleration and forces, give you the numerical information you need to fully understand the performance of your design. As you make design changes, you can compare the data to verify design improvement.

The Benefits – Recover Cost in One Use or Less

Use it once and Dynamic Designer will show you there is a definite need for it.”
– Bruce Emerson
Ward Machine Tool

Because engineering questions get answered very fast, without the time and cost of building and testing physical assemblies, it is very typical that Dynamic Designer customers recover the cost of the software within the first project. In addition to the time and cost savings, customers also note qualitative benefits to their designs, such as the ability to consider more designs, reduce overall risk , and produce more valuable information early in the design process. The customer success stories detail the use of Dynamic Designer in real customer situations.

Validate Your Design Inside Autodesk Inventor

Autodesk Inventor gives you world-class capabilities to design and build realistic 3D solid models representing theform of your parts. Inventor also allows you to create assemblies of the 3D solid parts in order to allow you to clearly understand whether the parts will properly fittogether as an assembly. What Inventor will not do is provide you with the ability to know if your design will actually meet it’s intended (and sometimes unintended) performance criteria? To determine if a design will perform as expected, the physical assembly is produced and a series of costly lab or field tests are done. This testing usually produces several design changes and the process continues until all production performance criteria are met.

The problem with this is that design validation is done too late in the process.

Simulate all aspects of mechanism motion.

Motion Professional is the complete virtual testing package for designers and engineer. Using animations and XY plots you will size motors/actuators, determine power consumption, layout linkages, develop cams, understand gear drives, size springs/dampers, determine how contacting parts behave, generate operating loads suitable for use by Finite Element Analysis, and much much more. Knowing this information will help you answer two fundamental engineering questions: “Will it work?” and “Will it break?”. If you are a designer or engineer interested in understanding the performance aspects of your design before physical prototyping, you need Motion Professional.

How to use Dynamic Designer Motion Professional

Product Applications

Mechanism Animation

You will animate mechanisms based on the assembly constraints, any additional constraints, and actuators you put in the model. AVCR-type interface provides complete and intuitive animation control. Animations are ideally suited to visualize the physical motion of your mechanism. In addition to seeing the motion you can save it to an AVI (movie) or a VRML (3D animated web format) file.

For more detailed motion analysis, you will visualize animations synchronized with XY plots of engineering data. You will use plots and mechanism motion together to identify possible system failure, part breakage, and safety issues.

Moving Interference Detection

Have you ever built a mechanism containing interfering parts? With Motion Professional you can eliminate interferences before you build the physical hardware. You will check forinterferences between parts as the mechanism moves through the real operating range. In addition, you can tell the software to find the first occurrence of an interference or to calculate the minimum distance between parts. An intuitive interference browser lists all steps containing part interferences and selecting an interference highlights it in the model.

Engineering Data

You will use the engineering data available in Motion Professional to really understand if your mechanism will work. Animations are perfect for getting a basic understanding of the mechanism and communicating that understanding to others. XY Plots are critical to gain intimate knowledge of how the mechanism works. With Motion Professional you can plotdisplacement, velocity, acceleration and reaction load/moment engineering data. Presented in XY plots, the raw engineering information is complimented with computed information like power consumption, kinetic energy, potential energy, and momentum. The XY plots will help you identify key events by allowing you to overlay multiple values on a single plot and creating multiple plots. For additional and customized data analysis, the underlying numerical data can be exported to Excel.

Contacts

The motion of many mechanisms results from contacting parts. For example, consider a sprocket contacting a chain, a latch contacting a hook, a cam driving linkages, and backlashing gears. Simulating contacting parts is as simple as selecting the two (or more) contacting parts, specifying the associated materials, and running a simulation. The resulting output is accurate 3D motion and XY plots of the underlying information.

Dynamic Designer supports both 3D solid-to-solid and 2D curve-based contacts. The combination provides both power and efficiency. 3D contacts are the most general/powerful while 2D contacts are more efficient. Dynamic and static friction effects can be accounted for in both forms of contacts.

In addition to animation visualization tools, you can plot numerous useful engineering data including contact force and reaction loads. These data will help you quantify important design criteria like bearing loads and part size.

Cams and Gears

You will be able to understand complex cam and gear mechanisms using Dynamic Designer Motion Professional. There are two ways to incorporate cams and gears into your motion simulation: usingcontacts or kinematic cam and gear elements. Contact capabilities, discussed above, provide tremendous flexibility and will help identify cam liftoff and gear backlash situations. The kinematic cams and gears are very efficient, but will not show liftoff and backlash conditions. Kinematic cams are simple to define using either a point-to-curve or curve-to-curve. Kinematic gears are defined by simply coupling the motion of one constraint/joint to the motion of a second constraint/joint (e.g. one joint rotates 3 times for every single rotation of a second joint).

Dynamic Designer outputs valuable data to help you understand if your cam-driven and gear-driven mechanisms will work including animations, displacements, velocities, accelerations, and forces. You will use this information to size actuator systems, assesscam liftoff situations, limit gear backlash, and reduce part stress/strain.

Constraints/Joints

Mechanisms have parts connected, or constrained, together and move according to the connections. For example, a pendulum can rotate in a single plane relative to the part to which it is connected. Motion Professional offers a comprehensive list of constraints (or joints) to connect parts together. Examples include hinge (revolute), slider (translational),universal, ball (spherical) joints, and many more. Joint friction is available for each joint so that you can accuractely model the physical reality.

Force Driven Motion

Forces are constantly acting on the mechanisms you build. Motors apply a torque to drive a mechanism. Friction effects the actuator size required to drive your mechanism. Nonlinear springs load mechanisms. Dampers stabilize spring loaded parts. Motion Professionalhelps you build these forces, and many other, into your virtual prototype. Including these forces allows you to accurately model the physics of the mechanism.

Loads for Finite Element Analysis

If you use Finite Element Analysis (FEA) applications to answer the “Does it break” question by analyzing parts or assemblies that move, Motion Professional can provide information that can substantially increase the accuracy of your analyses. As parts or assemblies move, it becomes very difficult to know what loads to add to your FEA model, and in what position the worst case loading conditions occur. Motion Professional calculates accurate loading conditions, including inertia effects, and can help you determine where the maximum stresses will occur. Motion Professional supports direct interfaces to leading Inventor based FEA products such as DesignSpace.

Interfaces

Motion Professional opens to door of communications with complementary packages including popular FEA packages (DesignSpace) and high-end ADAMS virtual prototyping solutions.

Motion Builder

Motion Builder technology helps automate the motion simulation process making it available to even the most causal user. The Intellimotion builder is a wizard that helps you quickly build motion models. It logically takes you through each step, asking key questions and gathering information as it generates the motion model. The resulting model is ready to put into motion and see the results.

Motion Browser

Motion Browser technology helps automate the motion simulation process making it available to even the most causal user. There are two ways to interact with Dynamic Designer Products: through a pull down menu and through the Intellimotion browser. The browser is a seamless extension ofCAD tree tools. All Dynamic Designer functionality is available through the tree browser including motion model construction, simulation, and result viewing.

If you are concerned about how joint friction will effect your mechanism you will need Motion Professional.

Mechanism Animation and Moving Interference Detection

Animations and interference detection are fundamental to understand the functional performance of a mechanism. Consequently, all Dynamic Designer products support these features. Motion leverages the engineering data display capabilities by synchronizing engineering data (displacement, velocity, acceleration) XY plots with the animations. You will use plots and mechanism motion together to identify acceleration abnormalities, motion synchronization issues, and part enveloping problems.

See assembly motion and check for interferences.

Simply Motion is a subset of both Motion and Motion Professional. It adds motion to your Inventor assembly, generates animations, and checks for interference as your parts move. The designs can contain components like linkages, motors, actuators, and springs. Simply Motion should be used by designers who only need to visually verify the motion of their moving assembly, who need to check for interference as the parts move, and who are not concerned with the forces (e.g. friction, dampers, etc.) that act on their design. Using Simply Motion is typically as simple as adding an actuator (e.g. motor) to the existing assembly model. If you need to model more complicated mechanical components (cams, gears, latches, chains, belts, etc.) and/or use the underlying engineering data (displacements, velocities, accelerations, forces) to make design decisions, you should consider either Motion or Motion Professional.
