Study on Multi-condition Test of Wheel-rail Adhesion Coefficient Testing Machine

摘要

This paper presents a scheme of multi-conditions of wheel-rail adhesion ball-disc testing machine. It is composed of mechanical components, hydraulic components, control components and data processing system, and can be carried out different testing experiments under the conditions of different speed, temperature, humidity, loading, magnetic field, materials, lubricant and slide roll ratio. And it also can complete the rail material adhesion test conditions under the coupling action, in the experimental process, in the course of the experiment only through the different conditions combination, the adhesion coefficient can be tested under the coupling action of different conditions; At the same time using the data processing system, the test data are analyzed in the process of testing, realizing real-time graphics output and data storage and other functions.
