This file contains example models showing how to extend Simscape Multibody 3D models with physical effects modeled in Simscape. Simple demonstration models of hydromechanical and electromechanical systems are provided to show how to create complete system models to test integrated designs.
Please read the README.txt file to get started.

This is really helpful! I'm surprised this functionality is so hard to find, and not included in the SimScape Library.

hi steve, thanks for the SimMechanics-Simscape Interface library as well as the SimMechanics Contact Forces Library.

I'm using a dc motor to drive a worm gear which in turn drives the crank of a slider crank mechanism through the Rotational simmechanics interface. Now the mechanism is supposed to be non backdriveable because of the worm wheel, but it's not so. I'have uploaded the file here .

please tell me what i'm doing wrong.

thank you

Sorry found it

Cylinder_Lift/Translational Simscape Intf'. I get an error saying failing to load that. Where can I download that from?

Great video - beautiful models.



Added R2017a version and text for citing submission in other works. CAD models imported from Onshape are in the R2017a version.


Added 6 examples in R16b showing 3 methods of connecting 3D mechanical models to other domains. Contains library of blocks to simplify integration. Documentation for each example. Content for releases R16a and earlier is unchanged.

Updated license


Fixed broken hyperlink in submission description.


Added R2016a versions.


Fixed webinar link.


Updated link to video in "Description" field. No changes to files in submission.


Added R2013a version with additional examples (hinge with hard stop, slider crank with hardstop, slider crank with 2 motors).
