轨道车辆动力学性能与轨道条件密切相关

Track vehicles ' dynamic performance is related to the conditions of trackage closely

轨道车辆与轨道线路是一个相互作用的大系统,轨道车辆必须也只能在一定轨道条件下满足动力学性能要求。因此,车辆验收运行试验也应该在规定的线路条件下进行,线路条件除平纵断面及线形变化外,还应包括各类轨道不平顺。

Track vehicles and trackage constitute a system in which they are acting each other.Track vehicles must satisfy the need of dynamic performance only on the basis of given conditions of trackage.Therefore ,the running test of vehicles for check and acception also have to be carry out in the prescriptive conditions of trackage which con-sist of plane and vertical section of the line ,their shapes change and various track irregularity.
