Abstract

A motorcycle engine shell is taken as the research object in the paper in order to reduce the noise radiation of motorcycle engine. The noise radiation of the engine shell is analyzed by the finite element method and boundary element method ( FEM / BEM ), and the frequency range of the noise radiation and the critical region are determined. Combining with sound intensity test, it is proved that the calculation result of the software is correct. According to the simulation results, the engine shell structure was optimized, and the noise radiation of the optimized model was predicted. Comparing the noise test before and after the model optimization, the results show that the optimized engine shell surface radiated noise is reduced about 4dB.
