摘　　要：本文针对空气润滑轴承刚度低的缺点,提出了一种主动节流器。通过这种主动节流器对轴承压力进行反馈控制,从而达到提高轴承刚度的目的。理论分析和计算表明,在一定的载荷范围内,具有这种主动节流器的气体润滑轴承的刚度具有明显提高。An elastic-baffles' active restrictor for obtaining a high stiffness aerostatic bearing is presented. The theoretical model of the bearing is given for a case of aerostatic journal bearing. Load versus displacement data were determined theoretically. The results obtained confirmed very high stiffnes's of the bearing with an elastic-baffles' active restrictor.
