摘　　要：研究双曲正切包装系统在矩形脉冲作用下的冲击响应。结果表明：脉冲幅值ｕｍ、系统Ｆｍ及阻尼ξ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 rectangular pulse. It is shown that the effect of the pulse peak m, system parameter F m and damping factor ξ on shock spectrum and damage boundary curve is noticeable, and that the hyperbolic tangent packaging system is essentially different from the cubic of tangent packaging system.

关 键 词：非线性 缓冲包装 冲击谱 破损曲线 矩形脉冲
