摘要/Abstract

摘要： 将频率视为一种新的特征参数来分析振动特性.首先提出了振动特征频率提取原理，通过快速点磨削振动特征提取试验获得了特征频率函数，随后分析了加工/空载状态下不同水平的工艺参数对磨削振动的影响，并结合砂轮与工件间的接触和能量传递关系分析了特征频率的变化规律.结果表明，加工特征频率始终小于空载特征频率，特征频率的相对偏差随砂轮线速度的增大而减小，随磨削深度、进给速度的增大而增大，同时比较了各工艺参数对特征频率的影响权重，提出了改善加工效率的思路.

关键词: 磨削振动;特征频率;工艺参数;快速点磨削;相对偏差

Abstract: In this paper， frequency is regarded as a new characteristic parameter to analyze vibration features. Firstly， the principle of vibration signal feature extraction was proposed， and the characteristic frequency function was obtained through the vibration feature extraction test of quick-point grinding. Then， the influence of different levels of technological parameters on grinding vibration under the machining or idle condition was analyzed. And the variation law of characteristic frequency was analyzed by comparing the contact and energy transfer relationship between the grinding wheel and workpiece. The results showed that the machining characteristic frequency is always smaller than the idle and the relative deviation of characteristic frequency decreases with the increase of the grinding wheel’s linear velocity， and increases with the increase of grinding depth and feed velocity. At the same time， the influence weight of each technological parameter on the characteristic frequency was compared， and the idea of improving the machining efficiency was put forward.

Key words: grinding vibration; characteristic frequency; technological parameter; quick-point grinding; relative deviation
