１提速客车装用防滑器的必要性（１）制动粘着系数是车辆基础制动设计的基本参数之一，提速客车一般选取湿轨面状态粘着系数值的１．１倍～１．２倍作为基本设计参数。我国制动粘着系数的测试研究结果表明，对应某一运行速度的粘着系数是一组正态分布随机变量。我们选取的... (1) The brake adhesion coefficient is one of the basic parameters of the vehicle foundation brake design, speeding the bus generally selected wet rail surface state adhesion coefficient value of 1.1 times to 1.2 times as Basic design parameters. The test results of the brake adhesion coefficient in China show that the adhesion coefficient corresponding to a certain running speed is a set of normal distribution random variables. We choose ...
