SimMechanics Demos

SimMechanics simulates translational and rotational motion of rigid bodies connected together by joints and actuated by forces and torques.

The demos are listed in this table from simpler to more advanced. They will acquaint you with some of the features of SimMechanics and how you can use SimMechanics with other MathWorks products.

Pendulum Models

Simple Pendulum: A rod swinging by one revolute joint

Double Pendulum: Two connected rods swinging by two revolute joints

Double Pendulum with Stiction: Two swinging rods slowed by sticky friction
