摘要
水下爆炸在极短的时间内产生巨大的冲击加速度,引起舰船上人员严重损伤,大大降低人员的作业能力。对人体冲击损伤程度的评估是评价舰船作业能力的重要依据。由于人群的广泛差异性,导致人体对冲击的耐受能力具有广泛差异性,不同的个体发生特定类型的损伤时的阈值水平也是不同的。总结了在舰船冲击损伤研究领域经常使用的各种人体冲击损伤评估方法,并提出了评估整个人体冲击损伤程度的流程。目前在使用这些评估方法在进行冲击损伤预测时需要专家的指导和参与,确定适当的个体或环境参数。对于每一个具体问题,最好采用多个耐受性标准和评估方法进行交叉引用或前后对照,才能得到比较可靠的评估结果。
Many injury assessment functions commonly used to evaluate the probability of human injury from ship shock are discussed, and the sketch map of human injury assessment methodology from shock motions is presented. Appropriate experts are required when using these assessment methods to predict the possibility of human injury. For a specific problem, it is better to use several functions and tolerance criteria simultanueously or successively for cross-reference and to take shape of a reliable assessment methodology.
