装药量对重力式码头侵爆毁伤效应的影响

Damage Effect of Charge Quantity on Gravity Wharf

为研究钻地弹作用下的重力式码头侵爆毁伤效应,采用数值模拟方法分析装药量对毁伤效应的影响,采用Lagrange算法与Lagrange/Euler耦合算法转换,实现侵彻效应和爆炸效应的连续计算,将经验公式结果与模拟结果比较,验证数值模拟方法的正确性。研究表明:装药量对码头毁伤效应的影响显著,两者服从非线性单调递增关系。

To analyze gravity wharf’s damage effects under the action of earth-boring bombs, the paper applies numerical simulation methods such as Lagrange and Lagrange/Euler coupling algorithms, to continuously calculate penetration and explosion effects, and compares the results with those obtained by empirical formula. It shows that the charge quantity has a significant influence on damage effects, and the former has a nonlinear and monotonous increasing relationship with the latter.
