水面舰艇舰员水下爆炸冲击防护研究

目的 研究减小不同姿态水面舰艇员水下爆炸冲击响应的方法。方法 通过建立水面舰艇舰员水下爆炸冲击响应集中参数模型，研究水下爆炸作用下不同结构参数对立姿、坐姿、行走状态下水面舰艇舰员冲击响应的影响。结果 对于坐姿舰员，增大甲板与座椅之间的阻尼比和刚度比，骨盆的冲击响应减小；对于立姿舰员，增大甲板的阻尼系数，下肢的冲击响应减小；对于行走舰员，增大甲板的阻尼系数，下肢的冲击响应减小。结论 可通过在甲板上加装抗冲击座椅或敷设抗冲击材料，增大甲板与座椅之间的阻尼比和刚度比或甲板的阻尼系数，减小水面舰艇员的冲击响应。

Research on the shock protection of surface ship crew subjected to underwater explosion

Objective To study the methods of reducing the shock response of surface ship crew by under water explosion.Method The shock response lumped parameter models were established to study the influence on surface ship crew with different structure parameters in standing,sitting and walking posture.Results For ship crew with sitting posture,the shock response of the pelvis could be reduced by enlarging the damping ratio and stiffness ratio between the deck and the chair.For ship crew with both standing posture a...
