摘要
本文采用有限元分析和实验模态分析方法对带有加强板的油底壳的振动进行分析。在该模型基础上,通过改变该模型的加强板结构来进行改进。结果表明,改变加强板结构可以减小油底壳的振动,进而降低了发动机的噪声。
In this paper, vibration of oil pan with reinforcing plate is analyzed through the method of finite element and experiment mode. According to this model, we try to modify the structure of the reinforcing plate to improve the stiffness of the whole model. The result shows that these structural changes may help to lower the vibration of the oil pan, and finally reduce the radiated noise.
