摘要
机载事故记录仪（即俗称“黑匣子”）要求在飞机坠毁时其存储、读取功能有效。对 其耐冲击性能有特殊要求，根据国际标准，对机载事故记录仪要求在幅值３４００ｇ，脉 宽６．５ｍｓ的半正弦波冲击条件下，检验其抗冲击性能，以保证事故记录仪在飞机坠 毁时数据能正常读取。本文介绍一种简易的能实现该高能量冲击环境的试验方法。
The function of saving and reading data of airborne event recorder (black box) should be available in clashing. According to international standard, there are special need to the capability of this airborne event recorder against shocking, it should be tested in the shocking condition of 3400g, 6. 5ms, half-sine pulse to keep the data of Airborne Event Recorder available in clashing. This paper introduces a sample method of high energy shock environment test.
