摘要
Abstract
Internal abnormal noises may occur sometimes in high-speed trains operation. In this study, the tests of internal noise in the coaches and roughness of the corresponding wheels are carried out before and after re-profiling of the wheels. Through analysis the different characters of noise and roughness before and after re-profiling of the wheels, it is found that the wheels of the coaches with abnormal internal noise are seriously polygonal. The polygonal wheels are improved by re-profiling and the level of interior noise is reduced.The result of study indicates that the wheel polygonal is the main reason to cause the internal abnormal noise.The level of polygonal wheels can be evaluated by the measurement of the internal noise.The most effective method to solve the abnormal noise is re-profiling of wheels currently.The conclusion plays an important role for polygonal wheel monitoring so as to prevent poor influence to high-speed trains due to the seriously polygonal of the wheels.关键词
