Rigid Flexible Multi-body Dynamics

A rigid-flexible multi-body system is a generic name for a broad category of dynamic systems that are assembled from a number of different components (with possibly each one of different material, shape and size), which are interconnected, and function together in order to withstand large overall motion, where the motion of each component remains constrained with respect to the others. In short, multi-body dynamics consists of analysis of rigid and/or deformable objects that are in bilateral contact via the joints. The examples of multi-body systems are encountered in many different fields of engineering: machine and robot manipulator in robotics, satellite and aircraft in aerospace engineering, road and rail vehicles in mechanical engineering or light deployable structures in civil engineering, to mention only a few. The rigid-flexible multi-body simulation capability are critical for initial/intermediate design and evaluation of vehicle/tank dynamics, helicopter/rotor dynamics, robots in synthetic battlefield environments, design optimization and control of advanced vehicle systems for enhanced maneuverability, ride comfort, safety and high operational speeds, prediction of loads which is a critical input in the design of components where light-weight, durability, and strength that are some of the competing objectives for industries.
