Simpack:
Multibody Simulation
Simpack is an advanced multibody simulation software designed to predict nonlinear motion in mechanical and mechatronic systems with high accuracy. By creating and solving virtual 3D models, it enables engineers to visualize motion behavior, interaction forces, and stresses in detail.
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 built for high-frequency transient analyses, extending even into the acoustic range. The multibody simulation software is well-suited for complex nonlinear models with flexible bodies and strong shock contact. It allows engineers to study extreme transient effects and consider external influences in real-world applications.
