| Abstract: | This paper established a traction dynamic model of vehicle system.It deals with the process of automatic control of engine,the sliding of clutch,the slipping of driving wheels and the clearance of hitch point.Based on the model,six dynamic differential equations of traction system were derived.The authors discussed with details the simulation model for the process of start and acceleration of transport vehicle system.Taking the tractor Taishan 25 and its trailer as an example,this paper provided the simulation results.These results also apply the analysis of traction dynamic performance of truck and tractor. |
