摘　　要：研究双曲正切包装系统在后峰锯齿脉冲作用下的冲击响应。结果表明 :脉冲幅值 ¨um、系统参数Fm 及阻尼ζ 对系统冲击谱和破损边界曲线有显著的影响 ,且该包装系统与立方型和正切型包装系统在冲击响应上有着本质的区别。The shock response of hyperbolic tangent system is investigated under the action of final peak saw tooth shock pulse.It is shown that the effect of the pulse peak m,system parameter F mand damping ξ on shock spectrum and damage boundary curve is noticeable,and that the hyperbolic tangent packaging system is essentially different from the cubic or tangent packaging system.
