多孔状挤压油膜润滑铰机构动态特性研究

Investigation of the Dynamic Characteristics of Mechanism with Porous Squeeze Film Lubricated Joint

对多孔状挤压油膜阻尼器控制机构间隙效应的能力进行了探索性研究 .采用算例分析了多孔状挤压油膜铰对机构的动态特性的影响 ,同时对比分析了传统挤压油膜铰与多孔状挤压油膜铰的控制性能 .结果表明 ,多孔状挤压油膜铰可以有效地控制机构的间隙效应 。

The porous squeeze film joint was developed for controlling the clearance effect of mechanism. Illustrative examples were presented to show the effect of porous squeeze film joint on the dynamic characteristics of mechanism. The control ability of traditional squeeze film joint was compared with that of porous squeeze film joint under high impact loads. The results indicate that porous squeeze film joint can operate more effectively for the mechanism working with greater condition change.
