A study on calibration of measuring wheelsets using a wheel derailment test facilities

초록

Wheel derailment test facilities is a testing equipment to analyze variation of creep force according to wheel-rail tread profile, running speed of vehicle, vertical and lateral force, wheel/rail contact point, attack angle. The creep force affect vehicle derailment, especially climbing derailment. This system is composed of main frame, wheelset and rail disks driver, hydraulic actuator, controller, environmental chamber, safety system etc. I have calibrated the wheelset for measuring the derailment coefficient using the test equipment. To give a load of 5 tons each in the left and right wheels, the test equipment was rotated at a speed of 5 km /h. At this time, by the strain of the wheel could make calibration sheet.
