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。 Aim To study the method of reducing the impact of underwater explosions on surface naval vessels in different positions. Methods By establishing a centralized parameter model of underwater explosive impact response of surface ships, this paper studies the impact of different structural parameters on the impact response of surface ships in standing posture, sitting posture and walking condition under underwater explosion. Results For the sitting crew, the damping ratio and stiffness ratio between the deck and the seat are increased, the impact response of the pelvis is reduced. For the standing crew, the damping coefficient of the deck is increased, the impact response of the lower limbs is reduced, Members, increase the deck damping coefficient, the impact of lower limbs to reduce response. Conclusion The shock response of a surface naval vessel can be reduced by adding impact-resistant seats or laying impact-resistant materials on the deck to increase the damping ratio and stiffness ratio between the deck and the seat or the damping coefficient of the deck.
