%X 为研究复杂工况参数（主轴转速、进给量、切削深度等）对车削振动的动态耦合性影响，提出一种敏感点振动测试分析方法。以轴类零件数控车削加工工艺系统为研究对象，在工艺系统数字样机中加入复杂工况模型进行仿真测试以确定振动敏感点和不同工况下敏感点的振幅频率动态响应。实验结果表明：相对于主轴转速和切削深度，进给量对车削振动的影响最大，与数值模拟结果一致。<br>In order to study the dynamic effects of operating parameters (spindle speed, feed rate, cutting depth, etc.) on turning vibration, a method of testing and analyzing the vibration of sensitive point was proposed. Taking the numerical control turning process system of shaft parts as the research object, the complex working condition model was added to the digital prototype of the process system; then dynamic performance simulation test was carried out to determine the vibration sensitive points, the amplitude-frequency dynamic response would be recorded under different working conditions. The experimental results shown that the feed rate had the greatest influence on turning vibration relative to spindle speed and cutting depth, which was consistent with the numerical simulation results
