Research on Coupled Dynamic Model of Tracked Vehicles and Its Solving Method

Abstract EN

In order to conveniently analyze the dynamic performance of tracked vehicles, mathematic models are established based on the actual structure of vehicles and terrain mechanics when they are moving on the soft random terrain.

A discrete method is adopted to solve the coupled equations to calculate the acceleration of the vehicle’s mass center and tractive force of driving sprocket.

Computation results output by the model presented in this paper are compared with results given by the model, which has the same parameters, built in the multi-body dynamic software.

It shows that the steady state calculation results are basically consistent, while the model presented in this paper is more convenient to be used in the optimization of structure parameters of tracked vehicles.
