Simulate nonlinear motion of any mechanical system

Predict and visualize motion, coupling forces and stresses

Analyze complete frequency range

From static to full transient nonlinear analyses


Simpack: multibody simulation

Simpack is a general multibody simulation software which enables you to simulate the non-linear motion of any mechanical or mechatronic systems. With Simpack you can generate and solve virtual 3D models in order to predict and visualize motion, coupling forces and stresses.

Main capabilities

Complete frequency range, from static to full transient non-linear analyses.

Take all influences from different codes into account on the system behavior.

SIMPACK can handle “stiff” dynamic systems.

Suitable for shock contact.

Simpack advantages

    Investigate extreme transient phenomena within all application fields.
    • Gear changing.
    • Emergency breaking.
    • Loss of contact.
    Consider any external influences on the system.
    • Ground disturbances.
    • Aerodynamic.
    Take internal dynamics and control into account.

Simpack simulation software is particularly well-suited for high frequency transient analyses, even into the acoustic range. Simpack was primarily developed to handle complex nonlinear models with flexible bodies and harsh shock contact.

SIMPACK is used in the following industries






HiL / SiL.


Wind energy.
