Course Details

This course focuses on how to model rigid-body mechanical systems in the Simulink® environment using Simscape Multibody™ (formerly SimMechanics™).

Topics include:

  • Modeling simple multibody systems
  • Creating custom geometries and compound bodies
  • Creating reusable models of mechanical systems
  • Assembling, guiding, and verifying mechanisms
  • Importing models from CAD software
  • Combining Simulink, Simscape™, and Simscape Multibody blocks

  • Parameterizing bodies for reuse

Assembling Mechanisms

Objective: Define and configure kinematics of a multibody machine in Simscape Multibody.

  • Reusing existing components
  • Specifying degrees of freedom
  • Sensing and logging simulation results
  • Adding stiffness and damping to joints
  • Setting initial conditions
  • Guiding and verifying an assembled mechanism

Importing CAD Models

Objective: Import existing parts and mechanisms from CAD platforms into Simscape Multibody.

  • Visualizing bodies with CAD geometries
  • Identifying the different CAD import workflows
  • Exporting from CAD software
