The Finite Element Analysisi of High Precision and High Range Pressurizing Mechanism

通过SolidWorks软件建立了高精度、高量程加压机构的三维模型;采用ANSYS软件建立了有限元计算模型。通过静力分析,得出了加压机构的应力、变形结果;通过模态分析,得出了加压机构1~6阶的固有频率、振型。根据计算结果得出加压机构的结构刚度、强度较好;相邻阶次的固有频率差别较小,动态性能较好。对加压机构进行拓扑优化,得出优化结果,为设计提供改进方向。

The three-dimensional model of high precision and high range pressurizing mechanism is established by Solid Works software;the finite element calculation model is established by ANSYS software.Through static analysis,the stress and deformation results of the pressurizing mechanism are obtained.Through modal analysis,the natural frequencies and mode shapes of the 1st to 6th order of the headstock are obtained.According to the calculation results,it is known that the structural rigidity and strength of the pressurizing mechanism are better.The natural frequency difference of adjacent orders is small,and the dynamic performance is better.The topology optimization of the compression mechanism is carried out,and the optimization result is obtained,which provides a reference for the subsequent design.
