Abstract: In this study, the potential attenuation performance of an metal foam cushion inserted between standing-man and ship deck is investigated theoretically. An 5-DOF lumped-parameter model is used to predict the standing-man’s biodynamic responses. The cushion is modeled by rigid-perfectly plastic-locking（RPPL）model. The influence of critical buckling force level and some other design factors on the attenuation performance of the foam cushion is discussed in detail. Some general design rules are also presented.

Key words: vibration and wave, polymer foam cushion, personnel, attenuation performance

摘要： 为分析铺设在舱室甲板上的用以吸收从甲板传递到人体的水下爆炸冲击能量的低密度泡沫金属地砖，建立了五自由度人体模型，并利用刚塑性本构模型模拟地砖的冲击响应。利用所建立的理论模型，对地砖材料及几何特性在不同冲击输入下的人员防护效果进行细致的分析，并给出人员抗冲击设计的一些准则。
