     摘要：应用CATIA对集滤器进行了三维实体建模,利用试验和有限元法对其进行了模态分析。以达到降低集滤器振动的目的,本文从提高结构刚度的角度对集滤器三个部件的结构进行了有限元仿真改进设计,找到了一种较理想的集滤器低振动改进方案。

    Abstract: A three-dimensional solid model of a prefilter is established with CATIA software.Modal analysis results can be obtained by combining experiments with the finite element method.In order to reduce the vibration of the prefilter,the stiffness of the prefilter is increased by improving the structural design of the three components of the prefilter based on finite element simulation.One satisfying modified scheme is found to improve the vibration of the prefilter.
