This is a webinar on High-Fidelity Simulation of Dynamic Axisymmetric Structures with Process Automation using RecurDyn.

Drivetrain components are required to withstand large numbers of cycles and various dynamic loading events.

Accurate analysis of driveline components can be achieved by considering the dynamics in the system, as well as the structural characteristics of the components.

An example is the simulation of the flexible boot of a constant velocity (CV) joint assembly that is used in an off-highway application with extreme transmission angles. Multibody dynamics and nonlinear finite element analysis techniques are used to simulate the boot behavior.

The simulation techniques include replicating the assembly process and dynamic operation.

The validation of this simulation shows excellent correlation between the simulation and the test regarding the collapse of the two outer folds of the boot (which form dimples), the shape of the boot, and the contact between the folds, all when rotating with a large transmission angle.

Process automation was used to increase the efficiency of such simulations.
