摘要
提出了一种带有金属橡胶外环的自适应挤压油膜阻尼器ASFD MRR(AdaptiveSqueezeFilmDamperwithMetalRubberouter Ring) ,它利用环形金属橡胶的弹性变形来调整油膜间隙 ,以达到油膜阻尼器最佳的减振效果 ,所进行的实验研究表明 :对ASFD MRR减振机理的理论预测和实验结果具有良好的一致性 ,该阻尼器在优化设计下 ,油膜间隙可以得到良好的控制 ,能明显抑制非线性振动现象的发生 。
An ASFD/MRR (Adaptive Squeeze Film Damper with Metal Rubber outer Ring) was designed to improve the high non linearity of oil film force of conventional SFD (Squeeze Film Damper). The ASFD/MRR can effectively reduce vibration due to its ability of automatically adjusting the film clearance by elastic deformation of the metal rubber. Experimental results indicated that ASFD/MRR can control the clearance of the film and its oil film force characteristics are better than those of SFD. If ASFD/MRR can markedly restrain the occurrence of nonlinear vibration phenomenon such as bistable characteristic, lockup and non synchronous motion, it can be suitable for wider range of unbalance level.
