Various mechanical Computer Aided Engineering CAE approaches can be taken to simulate your systems with RecurDyn
• Multibody Dynamics Simulation - MBD
A multi body dynamics analysis is the analysis of the motion over time of a system of rigid bodies interconnected by joints and acted on by forces, and possibly driven by user-defined motions of specific bodies in the system. The forces acting on the bodies can be inter-body forces, like springs or contact, or externally applied forces, such as gravity or a driving force. RecurDyn provides an intuitive, easy-to-use environment for modeling and analyzing multi body dynamics.
• Finite Element Analysis
Finite Element Analysis enables you to predict and understand how a mechanical component will react under various loads and operating conditions. RecurDyn is the first MBD software to contain a mesher. Because of this, it is very simple and convenient to generate MFBD analyses. The mesher is very effective, even for complex geometry.
The mesher supports the creation of the following element types:
2-node beam (Beam2)
3-node tri shell (Shell3)
4-node quad shell (Shell4)
4-node tetra (Solid4)
5-node pyramid (Solid5)
6-node wedge (Solid6)
8-node hexa (Solid8)
10-node tetra (Solid10)
• Multi Flexible Body Dynamics Analysis
Multi Flexible Body Dynamics Analysis is a combined approach that can be taken to increase the accuracy of your simulation results. 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 Multi Body Dynamics 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 Multi Flexible Body Dynamics ( 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 replaced with a mesh from other FE software easily.
RecurDyn's Multi Flexible Body Dynamics solution allows convenient and easy modeling of Multi Flexible Body Dynamics and its effective analysis. An MultiBody Dynamics model can be easily converted to an Multi Flexible Body Dynamics model through the use of the RecurDyn's Auto Mesher. Durability analyses can be easily performed using the results of an Multi Flexible Body Dynamics simulation. Multi Flexible Body Dynamics has been directly embedded into various other toolkits as well, such as RecurDyn/MTT3D and RecurDyn/Belt.
