新型龙门砂带修磨机关键零件的优化分析

Optimization Analysis of Key Part of New Type Belt Grinding Machine

以某新型的龙门重型砂带修磨机为研究对象,运用SolidWorks对其中的关键零件进行三维建模。然后运用有限元分析软件ANSYS Workbench的模态分析子模块对顶升连接件进行模态分析,从而获得其固有频率和振型。通过三种不同材料的动态性能分析,并根据所得数据和振型图分析出该零件的薄弱环节,针对其薄弱环节提出改进途径。通过各种改进方法的比较,从而找出最优化的改进方法并确定其所对应的材料,为提高修磨机的刚度、避免共振提供理论依据。

In this paper,a new type of gantry heavy-duty grinding machine is studied,SolidWorks is used to model the key part in 3D.And the modal analysis on the jack-up connecting part is carried out by finite element analysis software ANSYS Workbench,to obtain the natural frequencies and vibration modes.Through the analysis of the dynamic performance of the part made of three different materials,according to the obtained data and modal analysis,the weak link of the part is found,and the improving approaches are proposed.Through the comparison of various improvement methods,we can find out the optimized improvement method and determine the corresponding material.The theoretical basis is provided for improving the rigidity of the grinding machine and avoiding resonance,so as to improve the dynamic performance of the grinding machine.
