摘要
针对低频隔振问题,基于动力反共振原理设计制作了一种新型液压式动力反共振隔振器。根据不同的试验条件,对惯性质量、负载等与隔振频率的关系进行了一系列试验研究,在试验结果的基础上考虑隔振器的体积刚度对动力学模型进行修正,修正后的隔振器模型能够较准确地预测隔振系统的频率特性。基于试验结果,从理论和试验两方面阐述了调节隔振器反共振频率的方法,提出了兼顾隔振效果的合理化建议。
A new type of hydraulic dynamic anti-resonance isolator is developed based on the principle of dynamic anti-resonance,it is used to attenuat low-frequency vibration.A series of experimental studies of the relationship between inertial mass,load and vibration isolation frequency are made under the different experiment conditions.Based on the experiment results,according to the volumetric stiffness of the isolator,the dynamic model is corrected,which can be used to predict the frequency characteristics of the vibration isolation system more accurately.Based on the experimental results,the method of adjusting the anti-resonance frequency of the vibration isolator is expounded from the theoretical and experimental aspects,and the reasonable suggestion is offered on the vibration isolation effect.
