Multi-flexible-body Dynamics

 

Multi-flexible-body Dynamics (MFBD) is a technology used to analyze the dynamic behavior of systems that include both rigid bodies and flexible bodies. It is a combination of Multi-Body Dynamics (MBD), which analyzes the rigid body motion, and the Finite Element Method (FEM), which analyzes the motion, stresses, and deformation within flexible bodies.

 

Advantages

 

  • Combines the Multi-Body Dynamics (MBD) and the Finite Element Method (FEM) into a single solver, making it faster and more robust than a co-simulation approach.

  • Supports two flexible body formulations: modal superposition and nodal (or mesh-based) method. Supports both nonlinear geometric deformation as well as nonlinear material formulations, such as plastic strain and large-strain rubber-like hyperelastic materials.

  • Accurately simulate a system containing rigid and flexible bodies. It is possible to simulate nonlinear elastic cases including contact and large deformation as well as linear elastic cases.
