Abstract

The combined FEM-BEM method used to get the frequency response of the vibration and the noise radiation was applied on a gear-box which was the main noise source on the ZH1130 single engine diesel. Based on the prototype using the method, various optimization designs on the component were carried out. And the final design was got through the topology optimization method. The final design was manufactured and the validation experiment was operated, the results show that the SPL of the 7^th point in the experiment reduce 1.2 dB.
