METHOD OF MEASURING A WHEEL UNLOADING OF A RAILWAY VEHICLE, CAPABLE OF MEASURING A WHEEL UNLOADING BY USING A BENDING FORCE GENERATED IN AN AXLE OF A RAILWAY VEHICLE

摘要

PURPOSE: A method of measuring a wheel unloading of a railway vehicle is provided to reduce an economic loss caused by disusing a wheel set having wheels after measuring a contact force between the wheels and rail because a wheel unloading can be measured through measuring a bending load of an axle by mounting a strain gauge on the axle.;CONSTITUTION: A method of measuring a wheel unloading of a railway vehicle is as follows. A measurement wheel set for measuring a wheel unloading is selected and a contact plane of a strain gauge is processed(S10). The strain gauge is attached to the axle of the measurement wheel set(S20). A measuring system for transmitting signals measured by the strain gauge is constituted(S40). A bending load of the axle is measured by using the strain gauge(S50). The wheel unloading is measured by using the measured bending load(S60).;COPYRIGHT KIPO 2012
