传统的静压气体径向轴承由于低刚度而存在着振动和运动精度不高的问题。为此 ,作者提出一种自主式气体轴承控制方案。这种新型轴承由检测轴颈位移的非接触式传感器 ,驱动轴颈的控制阀及调节整个系统的控制器组成。当有径向载荷作用时 ,自主式轴承能抑制轴颈位移并因此使轴承获得无穷刚度。给出了3种节流控制方案 ,并得到相应的实现无穷刚度的数值解 The traditional static pressure radial bearings due to the low stiffness and the existence of vibration and motion accuracy is not high. To this end, the author proposed an independent gas bearing control program. This new type of bearing consists of a non-contact sensor that detects journal displacement, a control valve that drives the journal, and a controller that regulates the entire system. When there is a radial load, the self-bearing can inhibit the journal displacement and thus make the bearing infinite rigidity. Three kinds of throttling control schemes are given, and corresponding numerical solutions for realizing infinite stiffness are obtained
