Abstract

Flexible structures are often important components of mechanical assemblies in motion. A flexible structure sometimes must go through assembly steps that cause it to be in a pre-stressed condition when in the starting position for operation. A virtual prototype of the assembly must also bring the model of the flexible structure into the same pre-stressed condition in order to obtain accurate simulation results. This case study is presented regarding the simulation of a constant velocity joint, with a focus on the flexible boot. The case study demonstrates that careful definition of the initial conditions of the boot and flexible body contacts yields high-fidelity simulation results.

How Multibody Dynamics Simulation Technology is Used

RecurDyn can simulate complex assemblies and structures such as can be found in a CV joint. Tools within RecurDyn can aid in the careful replication of initial, pre-loaded conditions. The initial conditions have a large effect on the fidelity of the simulation.
