Multibody Simulation with SimMechanics

Register to watch video

Steve Miller, MathWorks

In this webinar we demonstrate how to model and simulate multibody dynamics using SimMechanics.  We show you how to define your multibody system using blocks representing bodies, joints, constraints, and forces.  You will be able to simulate multibody dynamics in systems such as robots, vehicle suspensions, construction equipment, and landing gear.

This webinar includes demonstrations and explanations to show you how to:

  • Define bodies parameterized with MATLAB variables
  • Assemble the bodies with joints
  • Simulate multibody dynamics within Simulink
  • Review a 3D animation of the simulation results

Simulation of multibody dynamics starts with the model you build.  SimMechanics enables you to define modular mechanical components that can be easily reused in other systems.  The MATLAB variables you use to parameterize your model can be automatically tuned to meet design requirements, or tested throughout a given range to see their effect on system performance.  Combining SimMechanics models with Simscape components and control systems modeled in Simulink makes it possible to simulate and analyze your entire mechatronic system in a single simulation environment.
