Wear testing machine

for railway applications

The high speed wheel & rail contact simulation system is to analyze and measure all the matters between wheel and rail contact surface during the high speed rotation. The system is organized by the main frame, wheel & rail disk specimen, wheel & rail driving motor, radial & thrust load actuator, contact angle & attack angle adjuster, EMG brake, environmental chamber, main control system, sensors, and etc. There are various test can be done by this system such as rolling contact test (RCF test), adhesive strength test, wear test, etc. from subway to high speed train. In addition, the system has environmental simulation equipment of water, oil, wind, sand insertion with temperature control (-30℃~80℃).
