초록
This Paper deals with the measurement and analysis of the brake squeal noise, the wheel’s and block brake’s vibration. The squeal noise, a kind of self-excited vibration, is generated by the friction between the rim of the revolving wheel and the block brake. The goal of this paper is to investigate experimental the relation between brake squeal noise and vibration mode of railway wheel with block brake to the track of friction surface on tread of railway wheel and the tread rake angle of railway wheel. Experimental results with Mode Analysis and Run Mode Analysis show that vibration mode of railway wheel with block brake is related with brake squeal noise.
