RecurDyn Technologies - MFBD (Multi Flexible Body Dynamics)

A multi flexible body dynamics analysis is a simple extension of multi body dynamics in RecurDyn. An MFBD analysis can be composed by swapping flexible bodies for rigid ones. MFBD analysis capitalizes on the advantages of MBD analysis in RecurDyn, such as ease of modeling joints and external forces. The motion of the flexible bodies as well as the resulting stresses, strains, and deformation of these bodies can be examined directly from the results of an MFBD analysis in RecurDyn.

Features of MFBD Analysis in RecurDyn
- Rigid and flexible bodies can be easily connected together in the same model.
- The number of bodies to be treated as flexible can be adjusted, as well as the flexible body formulation between the
- modal and nodal methods. This allows for simulation time to be optimized based on the needs for fidelity in the results.
- Boundary conditions and forces applied to the flexible parts are controlled much more naturally and much more
- accurately than they are using rigid bodies to estimate the forces to be applied to isolated parts in finite element analysis afterward.
- Connections, joints, and force elements are preserved when converting a rigid body to a flexible one.
- A rigid body in a RecurDyn model can be easily replaced with a mesh from other FE software.
