Modeling Multibody Mechanical Systems with Simscape

Course Highlight

This one-day 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

Course objective

The aim of this course is to provide an introduction to Simscape Multibody software for modeling rigid body mechanical system. Themes of modeling simple multibody system and constraints are explored throughout the course.

Who Should Attend

This hands-on course is designed for engineers who wish to implement physical modeling using Simscape Multibody Software in the SIMULINK environment. Engineers, researchers, scientists, and managers working with systems level design will be shown an easy-to-use approach in using Simscape Multibody software.

Course Benefits

Upon the completion of the course, the participants will gain an understanding of Simscape Multbody software which is essential and useful for designing and building mechanical systems.


Participants need to attend our prerequisite course 'Comprehensive MATLAB' and 'Comprehensive SIMULINK' or have equivalent knowledge of MATLAB and SIMULINK basics . Please check with us for more details.
