主要研究内容:
① 分析受力;
② 建立行驶方程式;
③ 以图、表(或编程) 形式，按照评价指标， 确定汽车的动力性。
Main contents: ①Analysis is subjected to the reactions; ②Establishing the motion equation of vehicle; ③With the form of the diagram, the table or the plait distance), press the vehicle tractive evaluation index, make sure the motion of the vehicle.
In transient condition, power and torque all descend about 5%-6%.
