Abstract

The invention provides a wheel non-roundness detection method and device. After the dominant frequency sound pressure level of noise in the train operation process is determined, the wheel non-roundness corresponding to the dominant frequency sound pressure level is further determined according to a fitting function of the corresponding relationship of the wheel non-roundness and the sound pressure level. In the process, the noise in the vehicle is detected in the vehicle running process; the wheel non-roundness is judged according to the noise detection condition; the goal of reducing the detection cost on the premise of not influencing the normal operation of the vehicle is achieved.

Description

technical field [0001] The invention relates to a railway wheel detection technology, in particular to a method and device for detecting the out-of-roundness of a wheel. Background technique [0002] During the operation of EMU trains, the wheels are in direct contact with the rails, causing the wheel treads to be worn by the force of the wheels and rails. When the wear reaches a certain level, it will affect the smoothness and comfort of the wheel running, and in serious cases, it will pose a threat to the safety of vehicle operation. Therefore, it is necessary to detect the degree of wear of the wheel tread, and regularly repair the wheel according to the test results and safety standards. [0003] Currently, wheel tread wear is usually measured by wheel out-of-roundness. Wheel out-of-roundness refers to the polygonal characteristics of a wheel due to irregularities in the circumferential direction. figure 1 It is a schematic diagram of a system for obtaining wheel out-...
