Multibody Modeling

Model bodies, assemble them using joints and constraints, specify and sense dynamic quantities of interest

Simscape™ Multibody™ models are similar in composition to the systems they represent. A typical model comprises a multitude of bodies, joints and constraints, forces and torques, and sensors. Start your model by creating the subsystems to represent the bodies. Then, connect the subsystems with joints and constraints to define their kinematic relationships. Add forces and torques—or, equivalently, motion inputs—to drive the model and sensors to measure its dynamic response.

  • Bodies
    Model body geometries, inertias, colors, and frames
  • Assembly
    Connect bodies through joints, gears, and constraints
  • Dynamics
    Apply and sense force, torque, and motion
