摘要

摘要: 针对某机载设备环境振动故障问题，对故障现象进行了分析。采用硅橡胶和工业用毛毡作为隔振材料，提出了一种在设备安装平台上下表面采取减振措施的复合隔振方案。进行了振动环境飞行实测，得到了设备安装部位的环境振动信号。基于实测信号，采用试验手段，进行了设备安装平台的复合式隔振设计方案优选，给出了有效降低机载设备振动响应的最佳隔振设计方案。

Abstract: The aim of the present work is focused on the vibration isolation design for certain airborne equipment installing platform under environmental exciting of a propeller plane. Firstly, the phenomenon was analyzed for the vibration problem of the airborne equipment, and then a complex design for vibration suppression was proposed by introducing damping material, silicified rubber and industrial felt, on both sides of the installing platform. The vibration environment for the installing platform was recorded during a flight test. Based on this recorded signal, vibration test was conducted to determine the best complex design for the vibration suppression of airborne equipment, and the design parameters were obtained for the most effective vibration isolator.
