摘　　要：箱式热发射时,发动机喷流噪声产生的振动环境多采用试验测量,环境预示手段应用较少。本文应用AutoSEA2软件对某喷流噪声产生的振动进行计算分析,并与试验结果作一比较,发现预示结果与试验结果比较相符,在型号研制初期具有一定参考价值。When missiles launch from electropult, the vibration environment caused by engine jet noise measured by experiment frequently .Less foreshowing techniques are applied in this field .We apply AutoSEA2 in the analysis of the vibration caused by engine jet noise. Compared with experiment result, the computation result accord with it well. At the beginning of the Research ＆ Manufacture process , the computation result has some reference value.
