讨论了在激振响应中识别和确立主轴部件动态参数的实验方法,主轴部件物理多数变化时固有频率变化的情况以及该方法用于对VQC-20/40B镗铣加工中心主轴测试的实践。
The experimental method of identifying and establishing the dynamic parameters of the spindle components in the excitation response, the variation of the natural frequency when the physical components of the spindle components change most, and the practice of the method for testing the spindle of the VQC-20 / 40B boring and milling machining center are discussed.
