Multibody dynamics is the science of studying the motion of complex mechanical systems under the application of mechanical forces.
Multibody Dynamics (MBD) simulation software allows engineers to study and investigate the mechanical and mechatronic systems' kinematic and dynamic motion, enabling them to generate and solve virtual 3D models to predict and visualize motion, coupling forces and stresses.
Study systems from beginning to end — Multibody dynamics is used throughout the design cycle from initial concept to final detailed design.
With multibody dynamics simulation, engineers can:
- make informed decisions for quick design changes and study sub- and complete systems
- reduce the number of prototypes
- avoid costly last-minute changes
- speed up time to market
Thanks to its high-end technology, the SIMULIA multibody dynamics product line which inherits Simpack technology developed for more than 40 years, powers all of the SIMULIA applications and is available on the 3DEXPERIENCE platform.
MULTIBODY DYNAMICS SIMULATION APPLICATIONS
Rail Vehicle Dynamics Simulation
Rail vehicles are complex systems and their performance is determined by the interaction of multiple components. Multibody System Simulation (MBS) offers the only realistic solution to explore and solve the complete system dynamics, without requiring a physical prototype.

Automotive Vehicle Dynamics
Multibody systems simulation is used in the automotive industry to analyze suspension systems and predict how the vehicle will behave under various conditions.

Electromechanical Power Systems
Multibody systems simulation is used for power generation applications such as wind turbines, industrial motors and gearboxes as well as electric motor simulation.
