摘　　要：以某型号的凸轮轴磨床为研究对象,运用软件PTCCreo对其关键零件垫板进行了几何建模,然后运用有限元分析软件ANSYS Workbench集成研发平台对此零件进行了模态分析,获得其固有频率和振型,并根据振型图分析出其薄弱环节,针对其薄弱环节提出了5种改进途径,包含了11种改进方案。通过对改进后垫板的固有频率和质量增加的大小来评价这11种方案的好坏,最后找到合理的优化方案。为提高凸轮轴磨床垫板的动刚度、避免共振提供了理论依据,从而为提高凸轮轴磨床动态性能提供了依据。Take a certain type of camshaft grinding machine as the research object and use the software PTC Creo to geometrically model the key part plate, then the finite element analysis software ANSYS Workbench integrated research and development platform is used to do the modal analysis of the part to obtain its natural frequencies and vibration modes, and according to the vibration modes to work out the weak links, and 5 improvement ways including these 11 improved schemes are put forward according to the weak links. Through the increase of the natural frequency and quality of the improved plate to evaluate the size of 11 schemes are good or bad, and finally find a reasonable optimization scheme. This scheme provides a theoretical basis for improving the dynamic stiffness of the camshaft grinding machine and a- voiding the resonance, thus providing the basis for improving the dynamic performance of the camshaft grinding machine.
