Abstract

The embodiment of the invention provides an analog method and device for reproducing polygonization of a train wheel. The device comprises a hydraulic actuator cylinder (1), a force sensor (2), a bearing frame (3), an upper bearing seat (4), a photoelectric sensor (5), a traction motor (6), a coupling (7), an analog wheel axle (8), an analog wheel axle torque sensor (9), an analog wheel (10), an analog wheel axle rotation speed sensor (11), and an analog rail wheel (13). By applying high-frequency rotation speed fluctuation whose phase is controlled by the space rotation angle of the analog wheel on a rotation shaft of an analog wheel set, polygonization caused by cycle skidding of the wheel set is reproduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of train wheel measurement, in particular to a simulation method and equipment for reproducing train wheel polygons. Background technique [0002] The polygonal phenomenon of train wheels refers to the periodic non-uniform wear phenomenon of the wheel circumferential surface after the train has operated for a certain mileage, that is, the phenomenon that the circular wheels gradually lose their roundness and develop into polygonal shapes. This phenomenon may appear on both the moving axle wheel and the trailer axle wheel. Due to the polygonalization of train wheels, the smoothness of train operation is reduced, causing high-frequency impact between the wheels and the track, and the impact load will reduce the fatigue life of train components, affect the economy and safety of train operation, and generate noise affect the comfort of the train. [0003] The research on the polygonization of t...
