摘　　要：为了解决机载电子设备引线或焊点在振动环境中的失效甚至开裂问题,通过金相切片、应变测试、仿真分析等手段对某VPX模块振动故障进行研究,对振动造成的电路板应变量进行量化,为优化电子设备抗振设计提供参考。通过开展VPX模块应力应变的研究,对于提前预测可能发生的振动故障以及电子设备的优化设计具有重大意义。In order to solve the problem of failure or even cracking of leads or solder joints of airborne electronic equipment in a vibrating environment,based on the metallographic slicing,strain testing,simulation analysis and other methods,the vibration failure of a VPX module is studied,and the strain of the circuit board caused by vibration is quantified,which provides a reference for optimizing the anti-vibration design of electronic equipment.The research on the stress and strain of the VPX module is of great significance for predicting possible vibration failures in advance and optimizing the design of electronic equipment.
