小水线面双体船冲击试验响应测量方案

Research on measuring scheme of shock response in small waterline area catamaran anti-shock experiment

基于以数值仿真结果预报指导试验方案的思路,对典型小水线面双体船结构进行实体建模,运用声固耦合算法模拟了其在水下爆炸试验工况下的冲击响应,总结得出影响试验冲击响应数据的各关键爆炸参数,包括爆炸攻角、爆炸药量、爆炸方位及爆炸水深变化时双体船冲击响应分布规律,为相关双体船型抗冲击试验测点布置及响应趋势提供预报和参考。

Based on the idea of numerical simulation results directing the experiment scheme,typical small waterline area catamaran entity model was established, and the shock response of underwater explosion experimental condition was simulated by acoustic-structure coupling method. Then each explosion key parameter which mainly influence the shock response results besides explosion attack angle, explosion dosage, explosion place and explosion water depth was summarized, catamaran shock response distribution changed law with the variation of each explosion parameter was revealed,it can be the significant forecast and reference for measuring points setting and shock response trend of relevant catamaran hull anti-shock experiment.
