摘要
利用Pro/E软件建立某V型发动机油底壳三维实体模型,采用有限元分析软件MSC.NAS-TRAN计算油底壳的振动模态,并对油底壳进行结构灵敏度分析,根据计算分析结果提出相应的降噪措施。
3-dimensional model of the engine oil pan was established in Pro/E. The FE modal analysis and sensitivity analysis of the oil pan were carried out by MSC. Nastran. Based on the numerical results, the authors gives some measures to reduce noise of the engine oil pan.
