摘　　要：利用电磁轴承在性能调控与状态自感知方面的潜力,开发出一种基于电磁轴承与角接触球轴承混合支承的主动式主轴系统。采取所开发的主动式主轴系统原型,通过控制电磁轴承控制器输入参数,可以实现主轴系统的主动式阻尼,并能够抑制铣削加工中的颤振;通过电磁轴承向旋转状态下的主轴系统施加主动激励,利用电涡流位移传感器获取主轴响应,可以实现主轴系统不同转速下动态特性的主动式感知;最后,通过试验验证了所开发系统在颤振抑制和状态自感知方面的有效性。An active spindle system based on hybrid support of active magnetic bearing and angular contact ball bearing is developed by using potential of active magnetic bearing in performance control and state self-sensing.Utilizing developed active spindle system prototype,the active damping of the spindle system can be realized,and the chatter in milling can be suppressed by controlling input parameters of active magnetic bearing controller.The active excitation is applied to the spindle system under rotating state by active magnetic bearing,and the response of the spindle is obtained by eddy current displacement sensor,which can realize the active sensing of dynamic characteristics of the spindle system under different speed conditions.Finally,the effectiveness of developed system in chatter suppression and state self-sensing is verified by tests.
