一、从一些车辆螺旋弹簧的工作图中,可以知道,目前对试验负荷的理解,尚不一致。大部分车辆弹簧设计者,对试验负荷的选取,是按照铁路员工手册第六卷第八册上规定的公式:P_p=P_(cm)(1+K_(кон·эап)进行计算。在该负荷作用下的高度,比弹簧全压缩时高3毫米。但也有一些设计者,把上述的试验负叫作最大试验负荷,而把工作静负 First, from some of the vehicle coil spring work map, we can see that the current understanding of the test load is not the same. Most vehicle spring designers choose the test load in accordance with the formula: P_p = P_ (cm) (1 + K_ (кон · эап) given in Volume 8 of Book 6 of the Railway Staff Manual. Under the action of the height of the spring than the full compression of 3 mm high, but there are also some designers, the above test is called the maximum test load negative, and the static work load
