shock spectrum

Based on the data of packaging product dropping test and the shock spectrum, a new method is presented to determine the fragility of packaging products under complex excitation by the two index of critical acceleration and critical displacement.

以产品跌落试验实测数据为依据，讨论了一种基于易损零件冲击谱，用临界加速度和临界位移两个指标确定产品易损性的新方法。

Objective An analysis and measurement system was developed for use with shock spectrum testing spaceflight products.

目的考核产品的耐冲击能力,为冲击谱试验机研制一套测试分析系统.

According to the experimental results, the irregular change of time histories of particle vibration is discussed in the period of strong motion, and it is found that the Fourier spectrum can not describe the shock property of strong motion.

根据实验结果，对质点振动时间历史在强震阶段的不规则变化进行了讨论，发现Fourier谱不能描述强震脉冲作用的特征。

Meanwhile , the spectrum is also related to the shock wave velocity.

光谱的结构特征也依赖于激波的速度.

For investigating thermal character changing of matter with shock compression, we need to measure the time character of radiating spectrum of matter with shock compression and its temperature, that is to measure transient time-resolved spectrum and its temperature.

为了研究冲击加载下物质热特性的变化，需要测量冲击压缩态物质所发射脉冲热辐射光谱及温度的时间特性，即进行瞬态光谱的时间分辨测量及温度解析。
