Simpack:
Multibody Simulation
Simpack is a powerful multibody simulation software that enables the accurate prediction of nonlinear motion in mechanical and mechatronic systems. By generating and solving virtual 3D models, it allows users to visualize motion, coupling forces, and stresses with precision.
Core Capabilities
Analyze the complete frequency range, from static to full transient nonlinear behavior.
Account for all influences from different codes on system dynamics.
Handle stiff dynamic systems with high computational efficiency.
Accurately simulate shock and contact behavior for extreme conditions.
Advanced Multibody
Applications
Simpack is designed for high-frequency transient analyses, even into the acoustic range . The multibody software is ideal for complex nonlinear models with flexible bodies and harsh shock contact. It enables engineers to investigate extreme transient phenomena and account for external influences in real-world applications.
