| 摘 要： | 在对外圆磨床磨削工件的表面直波纹形状和分布情况的研究及磨削过程中对磨削表面质量影响较大的砂轮架模态试验测试的基础上,分析造成表面直波纹的有害频率。建立有限元模型进行数值计算并通过试验数据验证,分析各阶频率相应的振型,讨论减少磨削表面直波纹的方法。为下一步对该砂轮架系统进行灵敏度分析及结构动力修改提供可靠的依据。

| Abstract: | The study is based on mode test of grinding machine and the surface straight waviness distribution of the workpiece. The modes are calculated by numerical value method agreed well with the results of mode test . By analyzing the vibration shape according to FEM, the method to reduce the surface waviness are given which are available for the luther step to dynamic optimization. |
