RECURDYN

RecurDyn can perform the analysis with the MFBD(Multi Flexible Body Dynamics) model in which MBD(Multi Body Dynamics) model and FEM(Finite Element Method) model is mixed. MFBD can perform the analysis the rigid body motion and the flexible body motion simultaneously. For this simulation, the flexible body analysis is cooperated with the multibody analysis. In the MFBD product, there is two type of product, RFlex and FFlex. In the RFlex, the mode superposition method is used to analysis the linear system. In the FFlex, the full degree of freedom is used to analysis the linear and non linear system.

• Flexible analysis with the rigid body system is applied for the detailed deformation; the total system’s dynamic motion can be expressed with MBD.
• Analysis of dynamic stress and strain with system analysis.
• Analysis of dynamic and strain with timely varying inertia force
• Usage of FE model data made by external CAD and commercial mesher
• RFlex (Reduced Flex) and FFlex(Full Flex) solver in the MFBD solver
• Expression of RFlex body’s motion using the combination of the selected mode shape, made by Eigen analysis; Modal coefficient as the DOF and the scalar variable multiplied to the mode.
• Expression of FFlex body’s motion using the entire node’s DOF from meshed geometry.
