Study mechanism behaviour

Understanding engineering performance is challenging for intricate mechanical systems, like wing flaps or landing gears, sliding sunroofs or suspensions, or photocopiers and other mechanisms. Motion simulation uses multibody dynamics to calculate the reaction forces, torques, velocities, acceleration and more for mechanical systems.


You can directly convert CAD geometry and assembly constraints into an accurate motion model, or create your own multibody model from scratch. The embedded motion solver and robust post-processing capabilities enable you to study a broad range of mechanism behaviours.

Motion simulation capabilities

Rigid Body Dynamics

Perform detailed rigid body dynamics analyses. It’s easy to create your motion model directly from your CAD assembly through an automated conversion process based on assembly constraints, or you can create your model from scratch. You can also quickly model and simulate contact between rigid bodies.


Flexible Body Dynamics

By including the motion of flexible bodies, you can analyse elastic deformation and rigid body motion together. This facilitates a more accurate understanding of part and mechanism performance.​

Control System Integration

Simcenter gives you the ability to co-simulate mechanical designs coupled with control systems to verify whether the control system design is robust enough to control the dynamic mechanism and help eliminate costly changes later in development.


Time waveform Application

Time waveform replication (TWR) uses multibody dynamics capabilities to allow you to build a virtual test rig, calculate the frequency response of a given system, specify target signals, filter and condition the signals and, ultimately, produce conditioned drive signals using an iterative solution process.

Drivetrain, transmission & gears

Simcenter helps you create and simulate detailed drivetrain models. Simcenter brings in-depth, gearbox-specific ease of use into the multibody simulation process, so you can rapidly move from initial design specifications to accurate simulations. The discrete drivetrain capability also provides a convenient interface to simplify the modeling of complex chain, track and belt systems.

Interference Checking

Simcenter provides a true multibody dynamic solver that can compute the displacement and position of assembly components connected to springs, bushings and flexible bodies. Using your geometry directly lets you determine whether you need to make design changes to avoid interference issues.

Unlock new external model integration possibilities by adding a model to a real-time (RT) platform, such as a vehicle simulator. This helps you more accurately reflect the actual physics of a vehicle. Integrate with other multiphysics models and combine with RT simulators and hardware-in-loop (HiL). Re-use existing models or extend the accuracy of RT models by adding more degrees-of-freedom (DOF).
