目的评估水下非接触爆炸对船员的冲击安全性。方法根据船舶主要舱室部位的冲击环境参数,依据相关标准(GJB 2689-96)以及船员冲击环境损伤阈值,对3种计算工况下主要舱室部位冲击环境参数分别进行船员冲击安全性评估。结果随着爆炸距离的逐渐缩小,其主要舱室部位船员的冲击安全性逐渐降低,属安全区部位的百分比逐渐降低,中度损伤区和重度损伤区部位的百分比逐渐增高。结论水深基本相同时,某一当量爆炸物距船舷水平近、中、远3种距离均可造成试验船某些舱室部位船员的冲击损伤,应采取防护措施。
Purpose To assess the impact safety of underwater non-contact explosions on crew members. Methods Based on the impact environment parameters of the main cabin of the ship and according to the relevant standards (GJB 2689-96) and the damage threshold of the crew impact environment, the impact safety assessment of the impact on the main cabin site under the three kinds of calculation conditions was carried out respectively. As a result, the impact safety of crew members in the main cabin gradually decreased with the explosion distance gradually decreasing. The percentage of safety breeds in the cabin decreased gradually while the percentage of moderately injured and severely damaged areas gradually increased. Conclusions When the water depths are basically the same, an equivalent explosive is near the ship side level, and the three kinds of distances can cause impact damage to some crew members of the test vessel. Protective measures should be taken.
