Research and Development of Wheel/Rail Force Testing Method

Wheel/rail force is a basic element to determine the dynamic performances of rolling stock,and their safety and operation quality can be reflected by wheel/rail force.This paper discusses the traditional theory of wheel-rail force testing methods and related researches at home and abroad,and summarizes the classification of wheel/rail force test methods.The ground test includes shear method and rail bottom moment difference method and etc.The vehicle test is divided into direct and indirect test methods.With the continuous development of technology,new wheel/rail force testing methods and testing devices are emerging.At the same time,more accurate and efficient new methods are put forward.In the future,the ground testing method of wheel/rail force tends to be continuous testing,while the vehicle testing method tends to be more accurate and intelligent with the progress of sensors and other technologies.And the wheel/rail force testing devices will be much more adaptive.
