The rolling bearing test rig is designed to achieve the comparative test results between single-phase fluid and two-phase flow and fluid lubricated bearings,with evaluation indicators of average temperature of the outer ring and frictional work, and to realize the measurement of rolling bearings and motor speed,the average temperature of the outer ring of bearing,frictional work,load,and so on.

In this paper,the hardware interface circuit design and data acquisition as well as method of processing of software part for display of torque,rotating speed,axle temperature,displacement and speed in the monitoring system on the high speed roller test rig for cars are introduced.

In testing the dynamics performance of locomotives and rolling stock on the roller testing rig, the difference between the track wheel and the actual track may cause deviation of the test results.

The stability of SY97804 testing railway vehicle tested on the roller testing rig in the National Traction Power Laboratory is presented in detail, and the testing method is discussed.
