摘　　要：床身作为重要的支撑件是整个机床的基础,床身的刚度和稳定性会直接影响到被加工件的尺寸及表面精度。床身的固有频率是评价磨床动态性能的重要参数,提高床身的固有频率能够有效的提高床身的结构刚度。床身经模态分析后,直观的显示出了其结构在设计阶段存在的薄弱环节,通过对床身结构的改进提高了床身的固有频率;通过比较不同的改进方案得出了磨床床身最优的改进结果,为后续的磨床床身结构设计提供了理论依据和工程参考。The bed as an important support is the basis of the entire machine tool.The rigidity and stability of the bed will directly affect the size and surface accuracy of the workpiece.The natural frequency of the bed is an important parameter for evaluating the dynamic performance of the grinding machine.Increasing the natural frequency of the bed can effectively increase the structural rigidity of the bed.After the modal analysis of the bed,it visually shows the weak links in the design stage of the structure.The natural frequency of the bed could be increased by improving its structure.The optimal improvement results of grinder bed body was obtained by comparing different improvement schemes,which provide a theoretical basis and engineering reference for the subsequent structure design of the grinder bed.
