Research on Lightweight Design of Electronic Equipment of an Aircraft

某型飞机严酷的载机环境对其列装的电子设备的重量和结构可靠性提出了更高要求。文中通过整机布局优化、功能模块整合、主承载结构优化的并行设计方法对机载电子设备开展减重设计,并进行了结构动力学仿真分析。结果表明,在满足结构力学性能基础上,减重设计后的设备质量降低了13%,并通过了随机振动、冲击等环境适应性试验。文中采用并行设计的方法,实现了电子设备轻量化设计,可供电子设备结构设计参考。

The severe onboard environment of an aircraft puts forwards higher requirements for the weight and structural reliability of its electronic equipment.A parallel design method of optimizing the overall layout,integrating functional modules and optimizing the main load-bearing structure is adopted to carry out weight reduction design for airborne electronic equipment in this paper.And the structural dynamics simulation analysis is conducted.The results show that after weight reduction design,the weight of the equipment is reduced by 13%while the structural mechanical properties are satisfied,and the equipment has passed environmental adaptability tests such as random vibration and impact.The lightweight design of electronic equipment is achieved through parallel design methods,which can provide reference for the structural design of electronic equipment.
