摘要

考虑金属橡胶减振材料的优越性，设计了采用金属橡胶作减震器的减振方案用于空间飞行器仪器安装板的整体减振。建立了金属橡胶减振器的力学模型，确定了金属橡胶减振垫的结构设计参数及性能参数，并对采用整体减振设计的仪器安装板进行了数学仿真分析。最后，设计了仪器安装板的地面振动实验并进行了振动实验考核。实验结果表明，仿真分析结果与地面实验验证结果基本一致，刚度满足设计要求。相比于刚性连接形式，采用金属橡胶减振器进行整体减振后，在300 Hz以上测量点的振动响应幅值大大衰减；在300 Hz以下测量点的随机响应均方根值衰减量不低于56.5％，达到了减振设计效果。

Abstract

With the advantages of metal rubber materials in vibration damping

a vibration damping plan based on a metal-rubber vibration absorber was proposed to damp the vibration for the integrated instrument installation plate of a aerocraft. A mechanical model of the metal-rubber vibration absorber was established and the design and performance parameters of the metal damping pad structure were designed. Then the instrument installation plate designed with integrated vibration damping method was simulated. At last

a ground vibration experiment was designed to test the vibration of the instrument installation plate. The results show that the analysis results are in agreement with ground experiment ones basically

and the stiffness meets the design requirements. Furthermore

with the integrated vibration damping by the metal-rubber vibration absorber

the random vibration amplitudes of the measuring points on the plate has a remarkable energy attenuation above 300 Hz and the random response mean square root attenuation is no less than 56.5％ below 300 Hz as comparing to the instrument installation plate with a rigid connection.
