摘要
文章在建立汽车制动过程中的整车、制动器、车轮和制动油路动力学模型和数学模型的基础上 ,提出了一种利用四阶 RUNGE- KUTTA法结合计算机解三元一次微分方程组的方法对汽车直线紧急制动过程中瞬时车速和瞬时轮速进行了计算 ,并将实车的仿真计算值和试验值进行了比较 ,取得了满意的结果。
This paper puts forward an method of calculating the instant velocity of an automobile which is in urgent straight braking course and its wheel's rotary velocity by using RUNGE-KUTTA method.The dynamic and mathematic models of the whole automobile, the brake, the wheel and the oil tube are established respectively. A satisfactory result is obtained when the simulated and experimental results are compared.
