| 摘 要： | 船舶碰撞是船体结构在很短的时间内承受巨大碰撞载荷作用的一种复杂非线性动态响应过程。应用非线性有限元数值仿真方法研究了传统双层舷侧结构在正碰状况下的碰撞性能,分析碰撞过程中舷侧结构的损伤特点和吸能特性,为研究提高舷侧结构抗撞性提供参考。

| Abstract: | Ship collision is a complicated nonlinear dynamic response subjected to enormous impact load in very short time.By using the nonlinear finite element numerical simulation method,this paper studies the collision performance of the traditional double-sided structure in the vertical collision situation,and analyzes the injury deformation and energy absorption of the shipboard structure to provide reference for the improvement of the crashworthiness of the shipboard structure. |
