摘要
本文利用所建立的内燃机薄壁部件的有限元模型 ,分析了它的自振特性 ,并得到了试验的验证。通过改变薄壁部件局部刚度 ,对减小薄壁部件表面振动响应的几种方法进行了探讨。
In this paper,the vibration charactistics of the shell component is analyzed with the finite element method and verified by test results.Several methods to reduce the shell component surface vibration response by changing its local stiffness are discussed. The results provide bases for the shell components low noise design and its developing method.
