Optimizing the Sound Radiation of Oil Pan Based on ANSYS

摘要：

Based on FEM /BEM method, the oil pan models on the finite element and the semi-anechoic chamber boundary element were established. Based on the oil pan models and the engine operating conditions, the oil pan structure had been improved. Using ANSYS software, the oil pan models were optimized, the effect on reducing vibration and sound radiation were predicted by increasing the stiffener and the damping material of the oil pan. The tests on sound intensity and sound power of the diesel engine were carried out; the test results indicated that the oil pan model was right; the methods on reducing the vibration and the sound reduction of the oil pan such as the stiffener and the damping material were reliable.
