Motion Analysis

Integrated Multibody Dynamics Simulation

Understanding the operating environments for intricate mechanical systems – like the mechanisms in photocopiers, sliding automotive sunroofs, or aircraft wing flaps – can be challenging. Many CAD-based tools offer kinematic solutions that help designers cycle a mechanism through its mechanical path for interference checking. Kinematics alone, however, doesn’t provide all the critical information you need, such as the dynamic loads generated by moving parts that can be used to size motors.

Simcenter 3D offers multibody dynamics simulation capabilities that go beyond simple kinematics. Motion analysis calculates the reaction forces, torques, velocities, acceleration and more for mechanical systems. Simcenter 3D lets you directly convert CAD geometry and assembly constraints into an accurate motion model, while the embedded motion solver and robust postprocessing capabilities allow the study of a broad range of product behaviors.
