Research on Wheel/Rail Force Testing System for Rolling Stock

轮轨作用力的大小可反映列车运行的安全性与平稳性,测试系统采用单点测试的方法测试轮轨垂向力与轮轨横向力。主要研究轮轨作用力测试系统的原理与设计,该系统主要设计过程包括组桥方案设计、标定装置设计与标定加压系统设计三个方面。通过实验室与铁路现场对该测试系统进行可行性验证,表明该轮轨作用力测试系统具备试验可行性,可以投入现场使用。

The magnitude of wheel/rail force can reflect the safety and stability of train operation.The test system adopts the method of single point test to test wheel rail vertical force and wheel rail lateral force.It mainly studies the principle and design of the wheel rail force test system.The main design process of the system includes three aspects:the design of bridge assembly scheme,the design of calibration device and the design of calibration pressurization system.The feasibility verification of the test system through the laboratory and the railway field shows that the wheel/rail force test system is experimentally feasible and can be put into use on the site.
