摘要
传统的冲击试验缺乏对冲击环境模拟的真实性,因此对某试验冲击信号采用较为先进的改进的递归数字滤波器法进行了冲击响应谱计算。介绍了冲击响应谱的计算原理和冲击响应谱的分析算法。用MATLAB数据处理语言为平台,得到该冲击过程对应的冲击响应谱曲线。为了更好地进行人机对话,在编写冲击响应谱曲线的基础上,编写了冲击响应谱数据处理软件。通过试验验证了算法的正确性,为工程实践中的冲击响应谱分析提供了一种通用性相对较好的分析方法。
In traditional shock experiment,the authenticity of the shock environment simulation is not enough.By use of advanced and improved recursive digital filter method,the shock response spectrum（SRS）calculation of a test shocking signal was performed. The calculation principle and analysis algorithms of SRS were introduced.Taking MATLAB data processing language as platform,the shock response spectrum curve in process of shock was acquired.In order to have a better man-machine dialogue,on the basis of the shock response spectrum curve,the data processing software of the shock response spectrum was developed.The tests proved that this algorithm is correct and it can provide a better method for shock response spectrum analysis in engineering practice.
