一种CPCI总线的机载设备抗振设计

Anti-Vibration Design for Airborne Device on CPCI Bus

介绍了基于CPCI总线的机载电子设备的母版振动问题,从故障现象入手,对故障原因进行理论分析,借助仿真手段,比较结构设计改进前后的变化,通过环境实验,从理论和实践两方面解决了机载设备母版振动设计问题。

In this paper, vibration problem of the motherboard of airborne electronic device on CPCI bus is described. Starting with the fault phenomenon, reasons of the problem are analyzed theoretically, and differences between before and after the de-sign improvement are compared with the simulation tools. After that, environmental experiment is conducted to prove the idea. In the end, the vibration problem of the motherboard of airborne device is solved theoretically and practically.
