Measuring method and application of dynamic friction coefficient of rail
摘要
Abstract
As a key factor to affect the running quality of the train,the friction coefficient is influenced by various factors when wheels are moving along the rails. Based on the important topic of measuring the friction coefficient of rails, this paper produced a method to measure the dynamic friction coefficient of rails by using pendulum tester. It described the measurement principles, structure and procedures. Using the 60 kg/m rail as experimental materials, researchers measured the dynamic friction coefficient of rail under different factors. Results show as follows: This method is able to measure the dynamic friction coefficient of rails by increasing dynamic strain device. Using this method to the actual engineering, notable effect is obtained to ensure the safety of railway operation.关键词
