| 摘 要： | 该文提出一种位置反馈自主控制静压气体轴承技术原理,能有效提高轴承的支撑刚度及回转精度.通过有限元数值计算法,按气体轴承刚度最大准则优化了固有节流轴承参数.在此基础上,给出了三种主动节流方式下的承载能力特性.计算结果表明:轴承固有节流参数优化是合理的,它能为自主控制轴承实现无穷刚度提供良好的负载范围.三种主动节流方式也为自主控制气体轴承提供了多样性选择.

| Abstract: | A scheme of active aerostatic bearing with displacement feedback is proposed.Its stiffness and rotation accuracy is advanced effectively.According to the numerical method of finite element,the bearing's parameters with inherent restrictors are optimized by the objective function of stiffness.Based on the analysis,the load capacity for three kinds of active control restriction modes are provided.The calculation results for three kinds of active restrictors show that the parameter optimization of aerostatic bearing with inherent restrictors is reasonable and it can provide good load capacity range for realizing infinite stiffness of the bearing.Three active restriction modes can provide more control selections for the active control bearing. |
