摘　　要：　基于冲击信号是一非周期信号,在冲击脉冲作用下通过测量冲击激励和在该激励下的冲击响应,对其进行频谱分析,最后得出振动传递率。本文论述了这一方法的理论依据以及可行性。The signal of impact is a nonperiodic signal. Through measuring the impact power and the impact response under the impact impulse, and analyzing the frequency spectrum, ultimately the vibration transmissibility of cushioning materials can be obtained. The theoretical foundation and the feasibility of the method were discussed.
