| 摘 要： | 介绍了装有ABS系统汽车的轮胎制动性能仿真方法.把整个制动过程按速度离散为若干个均匀的子区间,用有限元法计算在每个子区间的离散速度下制动器摩擦热损失率和轮胎与地面间摩擦能量损失率,然后根据能量守恒定律求出每个子区间上的制动时间增量,最终求得整个制动时间和制动距离.其中ABS的作用通过控制轮胎的角速度使其始终保持最佳滑移...

| Abstract: | A simulation method for tire braking performance of vehicle equipped with ABS system is presented.Specifically,the entire process of braking is divided into several sub-intervals with constant speed,and by using FEM to calculate the friction heat loss rate on disc brake and the friction energy loss rate between tire and ground at each discrete speed of sub-interval.Then the braking time increment in each sub-interval is obtained according to energy conservation law,and finally the total braking time and dis... |
