金属橡胶减振器对宇航单机随机振动的影响分析

The Impact Analysis of Metal Rubber Damper on the Random Vibration of the Aerospace Electronic Equipment

摘要: 宇航单机的元器件在随机振动过程中只能承受一定范围的响应加速度，当响应加速度值过高时，可能导致元器件失效。为了分析金属橡胶减振器对单机随机振动过程中响应加速度的影响，分别对不带减振器和带减振器的单机结构件进行了随机振动试验，获得了相应的数据。对比实验数据可知，增加减振器后单机在三个方向上的随机振动响应加速度都有不同程度的降低。该论文为单机的减振设计提供了试验数据和设计思路。

Abstract: In the process of random vibration, the aerospace electronic equipment can only bear a certain range of response acceleration, which may lead to failure of the components when the response acceleration value is too high. In order to analyze the impact of metal rubber damper on the re-sponse acceleration in the random vibration process of a aerospace electronic equipment, random vibration tests were carried out on the structural parts of the equipment without metal rubber damper and with metal rubber damper, and corresponding data were obtained. By comparing the experimental data, it can be seen that the response acceleration of the random vibration of the aerospace electronic equipment in three directions decreases in different degrees after adding the metal rubber damper. This paper provides experimental data and design ideas for damping design of the aerospace electronic equipment.
