摘　　要：在整个寿命周期内,航天器上的仪器设备可能经历分离冲击等具有高幅值、高频率特点的复杂冲击环境,可能对电子设备等产生致命危害,甚至导致飞行故障。本文对航天产品的复杂冲击环境模拟试验技术发展及其应用现状进行了概述。详细说明了各种冲击谱模拟试验方法的基本原理,并比较了每种方法的优缺点和适用范围。结合我国航天工程的发展要求和技术现状,为相关技术发展提出了建议。High g oscillatory shocks are frequently characterized by its high peak acceleration, high frequency content and short duration, are fatal to hardwares on spacecraft, payload, and launch vehicle, sometimes may lead to flight failure. The state of the art for techniques of simulation testing of SRS are summarized in this paper, including the mechanisms and limits of these methods, etc. Appropriate technological proposals are put forward on the basis of recognizing the demand and present situation of Chinese space technology.
