一、引言导弹在毛行过程中,要经历种种诸如发动机点火、关机、级间爆炸分离等冲击环境。为了制订弹上仪器设备的冲击环境条件,首先必须将所测得的真实环境数据处理成冲击响应谱。冲击谱的分析方法是很多的,最早的是簧片仪,以后发展到使用模拟计算机及数字计算机。簧片仪的特点是简单、直观,但由于它是机械装置,故分析频率不能太高;使用计算机的方法是比较理想的,问题是现在一般单位不易具备这样的条件。
I. INTRODUCTION Missiles in the wool line process, to go through all sorts of such as the engine ignition, shutdown, interstage explosion separation and other environmental impact. In order to establish the impact of environmental impact on the equipment on the bomb, first of all the measured real environment data must be processed into shock response spectrum. Impact spectrum analysis methods are many, the earliest is reed instrument, after the development to the use of analog computers and digital computers. Reed instrument is characterized by simple, intuitive, but because it is a mechanical device, so the analysis of the frequency can not be too high; the use of computer is the ideal method, the problem is that the general unit is not easy to have such conditions.
