一、纵向力试验当前,客运繁忙,坐车困难。为此,扩大客运列车编组,已成为较现实的措施。目前,扩编试验已从16辆、18辆、20辆、25辆,扩大到30多辆。扩大列车编组,在紧急制动时,列车中的纵向力有多大?一号缓冲器是否超过它的容量?这些都是要慎重考虑的问题。 First, the vertical force test At present, the bus busy, difficult car. Therefore, it has become a more realistic measure to expand the grouping of passenger trains. At present, the expansion test has expanded from 16, 18, 20, 25 vehicles to more than 30 vehicles. What is the longitudinal force in the train when the train is expanded and when the emergency brake is applied? Does the No. 1 buffer exceed its capacity? These are issues to be considered carefully.
