RecurDyn is a Computer Aided Engineering (CAE) software focused on Flexible Multibody Dynamics (MBD), with extended multiphysics capabilities. RecurDyn combines the power of an optimized recursive solver with superior contact technology, providing best-in-class simulation performances. The effectiveness of RecurDyn really comes out when approaching large-scale multibody models, including multiple contacts and flexible bodies.

Along with the powerful solver, RecurDyn features a natural Windows-based User Interface which is intuitive and easy to use, as well as a custom application development environment which enables users to automate complicated and/or tedious tasks.

Pre/Post environment specialized for MBD analysis

RecurDyn provides a fast and efficient modeling environment. The MBD optimized UI is based on the feedback from experts and engineers in the field of MBD.

Fast, accurate and diverse contact library

RecurDyn enables you to quickly and accurately analyze contacts in a complicated model using world-class contact algorithms. In addition, the Contact library is optimized for specific geometries such as ellipsoid, cylinder, or box.

Analysis of the motion of an assembly containing rigid and flexible bodies

It is possible to simulate nonlinear elastic cases including contact and large deformation as well as linear elastic cases. The processes of mesh creation and durability analysis are also supported within RecurDyn.

Scalability for multidisciplinary integrated analysis

RecurDyn provides the scalability for multidisciplinary integrated analysis such as simulation between the mechanical system and fluids through co-simulation with CFD software, control system simulation through co-simulation with Simulink, AMESIM, SimulationX (etc.), and optimal design of mechanical systems using robust optimization algorithms.

Flexible vs Rigid

MFBD (Multi Flexible Body Dynamics) in RecurDyn is a technology to analyze the dynamic behavior of systems which include both rigid bodies and flexible bodies. It is the combination of MBD (Multi-Body Dynamics) analyzing the rigid body motion and the Finite Element Method (FEM) to analyze the motion, stresses, and deformation within flexible bodies. RecurDyn’s solver combines with these two components into a single solver. RecurDyn is much faster and more robust than a co-simulation approach.

 

Toolkits for Every Dynamic Situation

Various toolkits support complex sub-systems, including: media transport products such as printers and copiers; track assemblies on products such as construction machinery, military vehicles and recreational vehicles; machinery components such as gears, belts, and chains. The toolkits allow the user to perform modeling for a specific industry field quickly and easily and then conduct an accurate analysis of complicated mechanical systems with specialized solvers.

Time Signal Generator

The RecurDyn/TSG finds an actuator signal in a RecurDyn model that causes an output signal (like a position, velocity, or acceleration) in the RecurDyn model to match an existing target signal provided by the user. This enables RecurDyn to reproduce a behavior that was measured in an actual mechanical system.
