You can try to import the CAD assemblies into Simscape Multibody using the "Simscape Multibody Link" plugin, which supports a couple of CAD applications, such as:
- SolidWorks®
- Autodesk Inventor®
- PTC®Creo™
You can learn more about this plugin by visiting the MathWorks documentation link below:
Once you have exported the CAD model to a Simscape Multibody-compatible XML file, use the "smimport" function to convert the XML file to a Simscape Multibody model.
You can learn more about "smimport" by visiting the MathWorks documentation link below:
Alternatively, you can also try to manually create a Simscape Multibody model by defining the bodies, joints, and other components using parameters extracted from the CAD model. This approach might be less precise in terms of geometric fidelity, but allows for simplifications that can speed up simulations.
To fit real geometry in MATLAB parameterization terms, you can:
- Identify Key Features: Determine which features of the real geometry are essential for the simulation and which can be simplified or omitted
- Simplify Geometry: Create simplified representations of the real geometry that capture the essential dynamics but reduce complexity
- Determine Parameters: Calculate the necessary parameters (e.g. mass, center of mass, moments of inertia) either directly from the CAD model or through approximations based on simplified shapes
- Create Custom Blocks: If necessary, create custom Simscape blocks to represent components that cannot be easily represented by standard blocks
Hope this helps!
