| 摘 要： | 利用有限元模态分析方法对装配式凸轮轴悬臂式数控装配机机架的模态特性进行了分析,得到了机架的前十阶固有频率和相应的振型,并对各阶振型进行了分析评价。根据分析结果,对机架的工作台及立柱提出了提高刚度和减轻重量的结构改进设计方案,并对改进后的机架进行了模态分析。结果表明:优化后的机架设计方案减轻了机架的重量并改善了结构的振动特性,提高了设计质量。

| Abstract: | The modal analysis of cantilever-type NC assembled frame for processing assembled camshaft was made by finite element method.The first ten steps natural frequencies and corresponding vibration modes of the frame were obtained,and each mode was analyzed and evaluated.According to the analysis,a modified structure design scheme for the bench and column of the frame was put forward to enhance the rigidity and lighten the weight,and the modal analysis of modified scheme was also made.The results show that the m... |
