摘要
文章介绍改进的递归数字滤波方法进行冲击响应谱的计算原理和分析方法。通过MATLAB数据处理平台编制一套通用的冲击响应谱曲线计算程序,可以快速分析得到冲击响应谱的曲线。通过对飞机起飞时刻冲击信号的冲击响应谱分析,为飞机机体结构安全及内部设备的环境振动设计提供重要依据。
The calculation principle and analysis method of impulse response spectrum by improved recursive digital filtering method are introduced.A set of general calculation program of shock response spectrum curve is compiled by MATLAB data processing platform,which can quickly analyze and obtain the curve of shock response spectrum.Through the analysis of the shock response spectrum of the impact signal during the take-off of the aircraft,it provides an important basis for the structural safety of the aircraft body and the environmental vibration design of the internal equipment.
