摘要
目前利用冲击响应谱作为参考的冲击实验在国防事业、国家经济生活中得到广泛的应用,冲击响应谱也成为国防事业和经济生活中重要的参考标准,分析对冲击响应谱造成影响的因素,将有利于对冲击响应谱规范,为更好实现冲击实验提供精确的参数设置。实验过程中为了得出冲击信号滤波带宽对冲击响应谱的影响,利用霍普金森杆产生高g值,窄带宽的冲击信号,再结合信号分析软件对得到的数据进行处理,得出滤波带宽影响冲击响应谱的等冲区的结论。
At present, shock test using shock response spectrum as a reference are widely used in the defense industry and the national economic life. Shock response spectrum has also become an important reference standard in the defense industry and the national economic life. Analysis of the factors influence on shock response spectrum will be helpful for shock response spectrum specification, provide accurate parameter setting In order to better realize the shock test. In order to find the effect of filter bandwidth of shock signal on shock response spectrum in the experimental process, it can use the Hopkinson rod to produce a high g value, narrow bandwidth shock signal, and combine with the signal analysis software for data processing, to draw the conclusion that filter bandwidth effect the buffer zone of shock response spectrum.
