MATLAB: How to use the Cycloidal Drive block from Simscape in a SimMechanics model

Question

When I try to connect the Cycloidal Drive block to elements of my multi-body SimMechanics model, it won't connect. Does anyone have a working example model that I can play with?

Thanks,

Morgan

Hi Morgan,

The Cycloidal Drive block is a SimDriveline block, which means it connects directly to other Simscape mechanical blocks (but not to SimMechanics). The reason is that SimMechanics uses a separate 3-D mechanical domain, while Simscape/SimDriveline is all 1-D rotation OR 1-D translation.

The way you connect Simscape blocks to a SimMechanics block is to place them along a joint primitive. There's a submission on the File Exchange which shows how you can do this.

Using the blocks from the above submission, you can interface your Simscape rotational domain with a SimMechanics revolute primitive as shown below.
