Analysis of dynamic characteristics for four-track vehicles by Bondgraph: dynamic characteristics of four-track vehicles in snow

摘要

The dynamic running performance of the four-track vehicle (known as crawler vehicle) in the deep snow is analyzed. The modeling of the vehicle is easily completed by use of the Bondgraph. The simulation results by use of Bondgraph software 20-simare as follows:The fundamental mechanism of the vehicle running in the deep snow is that the crawler unit is swung by the resistance of the snow around the center of the drive shaft. Furthermore the frequency and amplitude of the swing is changed with the amount of thesnow resistance.
