Dynamic Simulation of Small Crawler Chassis Turning Based on RecurDyn

A multi-body dynamics model and ground model of a small crawler chassis was built on software RecurDyn/Track (LM). The simulations of the small crawler chassis turning on hard and soft terrain are implemented respectively, and the results are analyzed and compared. The steering properties of crawler chassis turning on soft terrain are emphasized. The simulation results can provide some theoretical guidance for crawler chassis steering performance.
