双层混合隔振系统隔振效果评价与实验研究

为了对双层混合隔振系统进行全面评价,提出了一种全新的双层混合隔振系统隔振效果评价方法.该方法将混合隔振的评价指标定义为被动隔振指标与主动隔振指标之和,并在自行研制的磁悬浮隔振器上进行隔振实验.实验结果表明,该评价方法简便易行,能够准确地反映被动和主动隔振对不同频段隔振的贡献以及两者之间的相互影响,为进一步优化双层混合隔振器的设计提供了可靠依据.

Evaluation and Experimental Research on the Vibration-isolation Effect of Dual Layer Hybrid Vibration-isolation System

To evaluate dual layer hybrid vibration isolation system comprehensively,and the new evaluation method for the vibration-isolation effect is proposed.The evaluation index is defined as the sum of passive vibration-isolation and active vibration-isolation,and the method is tested on self-developed magnetic levitation vibration isolator.The result of experiment indicates that this evaluation method is simple and easy to do,and is able to precisely reflect the contributions of passive and active vibration-isol...
