一、引言在国防工业中,许多产品如火砲、舰艇、导弹、卫星等,其上的设备仪器,都要遇到各种不同的冲击环境。如火砲发射,舰艇受到深水炸弹的攻击,导弹发动机点火,级间爆炸分离等.为了制定产品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,冲击响应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 I. INTRODUCTION In the national defense industry, many products such as artillery, ships, missiles, satellites, etc., all have different impact environments on their equipment and instruments. Such as artillery firing, ships being attacked by deep-water bombs, missile engine ignition, interstage blasting separation, etc. In order to set the impact environment conditions of the product equipment, the measured real environment data must first be processed into impact response spectrum, impact response spectrum The analysis method is a lot of the earliest reed instrument, later developed to use analog computers and digital computers, reed instrument is characterized by simple, intuitive, but because it is a mechanical device, so the analysis of frequency
