作为机载设备装机的常用附件,机载安装架的结构设计不但要满足复杂装机接口的要求,还应将恶劣环境条件对机载设备的影响降至最低。文中简要介绍了一种集中式机载安装架的结构设计方法,并对随机振动条件下安装架上设备的动态响应以及加速度过载时安装架的强度和位移进行了仿真分析,确保安装架具有很好的隔振效果并满足载机隔振空间要求。
As a commonly used attachment of airborne equipment, the structural design of airborne mounting frame not only meets the requirements of complex installed interfaces, but also minimizes the impact of harsh environmental conditions on airborne equipment. In this paper, the structure design method of a centralized airborne mounting frame is briefly introduced. The dynamic response of the equipment on the mounting frame under random vibration and the strength and displacement of the mounting frame during acceleration overload are simulated and analyzed to ensure that the mounting frame has very good Good vibration isolation effect and meet the requirements of space vibration isolation.
