A rigid flexible coupling dynamics simulation of one type of tracked vehicle based on the RecurDyn

Abstract

In order to get the load and stress of the key parts of the tracked armored vehicle. A rigid flexible coupling dynamics model of tracked armored vehicle is established, also the simulation road is established based on typical test field. The simulation analysis accurately simulated dynamic characteristics of vehicle, and the transient response of torsion bar in typical road excitation is obtained. It is important that the dynamic load and dynamic stress history of the torsion bar are obtained. It avoids the difficulty of torsion bar load testing, and provides a new idea for the acquisition of complicated structure load and stress of tank and armored vehicle, also provides an important dynamic load and time stress data for the following fatigue calculation.
