铁道车辆在调车场编组列车时所承受的冲击力是最猛烈的。通常冲击力可由式(1)表示。由于货物的弹性变形和移动的影响,实际冲击力比式(1)的计算值要小。我们用式(3)给出冲击力系数的抽象定义。 F=(W_1+W_2)a (1) f=W_1a+KW_2a (2) F>f令 W_1a=f_1,得: K=(f-f_1)/(W_a) (3)式中 W_1——车辆自重; W_2——载重; a——车辆的加速度; F——假定车辆与货物两者为刚性时的冲击力; Railway vehicles in the shunting train when the group bear the brunt of the impact. Normal impact can be expressed by equation (1). Due to the elastic deformation and movement of the goods, the actual impact is smaller than the calculated value of (1). We use (3) to give an abstract definition of the impact coefficient. F = (W_1 + W_2) a (1) f = W_1a + KW_2a (2) F> f Let W_1a = f_1 be: K = (f-f_1) / (W_a) ; W_2 - load; a - the acceleration of the vehicle; F - the impact force assuming both the vehicle and the cargo are rigid;
