| Abstract: | A model for predicting the radiation noise from the engine sump was constructed and software was developed by Finite Element Method and Boundary Element Method. The radiation noise of a sump with multi-point excitation was predicted. The experiment results indicated that this calculation method was precise, providing a good basis for the optimized design of the engine with low noise. |
