Abstract：

On the basis of analysing characteristics of exhaust noise of pneumatic friction clutch and brake,conditions that muffler controlled the noise has to satisfy are suggested. Characteristics of filtering and reducing the noise for elementery units of the muffler are studied through test method.So assembly structure of the muffler are obtained and characteristics of reducing the noise for the muffler are thoroughly studied. 38dB (A)'s amount of reducing the noise is gained when this new type of muffler is spread and used in a test bed and in the factory reality.
