摘　　要：以某数控铣床主轴为研究对象,建立了轴和角接触轴承的等效动力学模型.研究了轴承等效刚度和预紧力参数对主轴系统固有频率影响规律,通过模态分析确定主轴部件的固有频率和振型,验证数控铣床主轴部件结构设计的合理性。It studies the rule that bearing equivalent stiffness and preload has an effect on the natural frequency of the spindle system. Dynamically equivalent model of the axis and the angular contact bearing is established. The natural frequency and mode of vibration are calculated, therefore, the design rationality of the spindle components is proven.
