摘要
利用有限元法对柴油机气缸盖进行了模态分析,获得了气缸盖的基本振型和相关频率,与试验结果进行比较,两者有较好的一致性,因而可利用所建立的有限元模型完成气缸盖的动态响应分析及设计优化。
The application of finite element method to carry out a modal analysis for the cylinder head of the diesel engine, the mode shapes and natural frequency of the cylinder head are obtained. The results of finite element analysis well coincide with that of modal test, the model can be used in the analysis of dynamic response and design optimization.
