摘要
论文针对板状网格模型破口面积的快速定量计算问题,设计了一种快速算法,并针对一批某鱼雷对某驱逐舰爆炸毁伤数值仿真结果进行了计算,验证了该算法的有效性。该算法应用主成分分析方法,可实现对各类板状结构产生的不规则破口区域面积的快速计算,可为相关结构物毁伤评估提供支撑。
This article proposes a fast and quantitative algorithm for calculating the break area of plate grid models.The effectiveness of the algorithm is verified by a batch of calculation results,which is obtained from the numerical simulation for a torpedo's explosion damage to a destroyer.This algorithm,which applies principal component analysis method,can quickly calculate the area of irregular break areas generated by various plate-like structures,supporting the damage assessment of related structures.
