摘　　要：在振动试验的耐振阶段,危险频率上的放大倍数越大,电子设备的性能和功能受到的影响越大,甚至造成产品的永久性损坏,这一理论有助于环境试验项目科学地辅助科研生产设计。本文研究了船用电子设备在振动试验时的危险频率及其放大倍数,以及改进设计后的振动试验数据采集图谱,总结出了可行的产品设计方案。这一研究进一步说明了振动试验在科研生产设计环节中的重要性和必要性。In the vibration resistance stage of vibration test, the greater the amplification of the dangerous frequency, the greater impact on the performance and function of electronic equipment,and even the permanent damage to products. This theory is helpful to assist the scientific research and production design of environmental test projects. This paper studies the dangerous frequency and magnification of Marine electronic equipment in vibration test, and the data acquisition map of vibration test after improved design, and summarizes the feasible product design scheme. This study further illustrates the importance and necessity of vibration test in the process of scientific research, production and design.
