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. Block brake cause friction noise and excessive braking noise makes passengers and operators uncomfortable. The goal of this paper is to investigate experimental the relation between brake squeal noise and behavior of block brake with railway wheel. Experimental results with MA and RMA show that behavior of railway vehicle block brakes is related with brake squeal noise.
