【Abstract】 In this paper, the methods such as spectrum and coherent analysis are used to analyse the noise characteristics of OE rotor system, consisting of rotor, bearing, volute, sealed ring and flow channel as an integrated whole. Applying the principle of noise reducing, an optimized silencer is designed based on the method of orthogonality regression and the method of solving optimum values, it makes the noise decrease 3～5 dB(A). The results of experimental tests are quite good and satisfactory.更多还原
