摘要:
 

利用显式非线性有限元动态分析技术, 对600吨船首部区域结构的碰撞特性进行了数值仿真研究。首先, 采用流固耦合法对船舶碰

撞的整个过程进行真实有效的仿真, 获得被撞船的损伤变形、碰撞速度和碰撞力的时序结果。然后, 采用附加质量法研究船首结构

耐撞性能, 对其结果进行比较。在此基础上, 进一步考察了撞击参数 (速度、角度等) 对被撞船首部区域结构碰撞特性的影响。

Abstract:
 

The study of numerical simulation of collision characteristics of a 600-ton ship’s bow is carried out by using

explicit nonlinear finite element dynamic analysis. Firstly, the fluid-solid coupling method is used to simulate

the whole process of ship collision, as a result of which the time series results of damage deformation, collision

velocity and collision force are obtained. Then the added mass method is used to study the crashworthiness of the

bow structure and the results are compared. On this basis, the impact of collision parameters (velocity, angle,

etc.) on collision characteristics of the bow of the collided ship is further investigated.
