水下非接触爆炸舰员抗冲击防护地板设计与试验

Design and test of underwater non-contact explosion shock protection floor for seamen

摘要

摘要:
目的为有效保护水面舰船舰员免受水下非接触爆炸所引起的冲击损伤，
方法在分析水面舰船人员冲击环境和安全限值的基础上，提出舰员抗冲击防护地板设计方法，设计一种具有非线性变刚度力学特性的新型抗冲击弹性地板。在模拟舰船典型中、重度冲击环境的冲击台试验中，对抗冲击弹性地板的防护效果进行验证和评估。
结果结果表明，抗冲击弹性地板可以衰减88%以上的冲击载荷，能有效降低对舰员的冲击损伤程度。
结论所做研究可为舰船冲击环境恶劣的部位提供有效的舰员抗冲击防护。

Abstract:
Objectives In order to more effectively protect the surface ship seamen from the shock injury caused by underwater non-contact explosion,
Methods the shock environments and safety limits for seafmen aboard surface ship are analyzed firstly. Then, the design method for human anti-shock flooring is put forward, and a new type of anti-shock elastic floor is designed which has nonlinear mechanical properties with variable stiffness. Finally, the protective effects of the anti-shock elastic flooring is validated and evaluated in the shock table test that simulates the typical medium and severe shock loads.
Results The test results indicate that the shock load attenuating rate of anti-shock elastic flooring is over 88%, which could reduce ship shock injury greatly.
Conclusions The research can provide effective shock protection for seamen in severe shock environment.
