讨论了脉冲激励幅值以及系统阻尼等对冲击谱的影响规律。
The regular pattern of influence on impact spectra by amplitude of pulse excitation and system damping was discussed.
在阻尼不是很大的情况下，速度脉冲效应是较大的。
The effect of velocity pulse is significant in low damp the case.
阻尼使非线性包装系统位移峰值和加速度峰值明显降低，但对脉冲持续时间几乎无影响。
The damping can obviously decrease the peaks of displacement and acceleration of nonlinearcushioning system, but has on effect on the pulse duration.
