摘要

针对舰载导弹存放架减振要求苛刻的特点,分析了高低频复合振动条件对减振器刚度的要求,得出大承重条件下难以满足低频减振要求.针对高频振动,应用金属橡胶和金属弹簧设计了一种复合减振装置,通过仿真实验验证了样机对高频振动的有效性.研制了试验样机,并进行了静态力学和动力学试验,得到减振器刚度为806.5 N/mm,系统有效隔振带>12.78 Hz,满足系统减振要求;同时分析了动力学试验加速度传递曲线双共振峰的原因是由于增加了俯仰自由度.

Abstract

To solve the problem of hard requirement of shipboard missile storage rack to resist vibration, the rigidity requirement of vibration isolation damper was analyzed under the condition of compound vibration including high and low frequency. The conclusion was gotten that it couldn't meet the requirement of low frequency vibration with heavy bearing. Against high frequency vibration, a new compound damper was developed using metal rubber and metal spring. Its effectivity for high frequency was determined through simulation experiment. The static mechanics test and dynamic test were done at last after model was produced and the result shown that its rigidity was 806.5 N/mm and its frequency-arrange to resist vibration effectively is no less-than 12.78 Hz, which meet the requirement of vibration isolation. And the cause of two formants occurred on the curve of accelerate transmission rate was explored that the pitch freedom was appeared for the dampers.
