Multibody Dynamics (MBD) simulation is essential for analyzing the motion, forces, and behavior of mechanical systems made up of interconnected parts. Using tools like ADAMS and Simpack, engineers can replicate real-world kinematics and dynamic behavior—such as linkages, rotating shafts, suspensions, or robotic arms—before physical testing.
Despite its advantages, MBD simulation presents its own challenges. Engineers must accurately model joints, constraints, contacts, and motion drivers, all while balancing computational performance and model fidelity. Misaligned constraints, unstable solvers, and improper damping assumptions can lead to inaccurate or unusable results. Additionally, vibration and fatigue analysis require precise post-processing and tuning of simulation parameters. Overcoming these barriers is critical for designing high-performance, reliable mechanical systems.
