STANDARD SPECIAL TEST SYSTEM STANDARD SPECIAL TEST SYSTEM RAIL TRANSIT Shrinkage wheel contact fatigueFriction and wear tester fretting fatigue tester J0l| overview Shrinkage wheel contact fatigueFriction and wear tester fretting fatigue tester It is mainly used to do the simulation fatigue testing of the contacting between wheel and rail, when the Shrinkage wheel and rail sample working under the given load & high speed rotation. It is operated based on the YB/T5345 "the fatigue test method of rolling metal material" The tester is used for fretting fatigue test of the wheel axle. The sample is prepared as shrinkage axle. It can test the stress changes of contacting area between the wheel and axle when simulating the vehicle's running condition Shrinkage wheel contact fatigue Friction and wear tester The test bench is four-column frame with cast iron base. The vehicle wheel and rail wheel is driven by servo motor. The test bench mainly simulate the condition of wheels and rails when running.It is designed to study the contacting fatigue and the friction and wear. The structure of test bench is as above sketch,it is composed of iron plate,electronic hydraulic servo host, bearing seat, environmental box, wheel hold seat, upper and lower platform, frequency conversion speed motor and hydraulic station. 031 Specifications and main parameters —Type Parameter
