摘要
采用非线性动态响应分析方法,使用ANASYS/LS-DYNA显式动力分析软件,对船首和船舷垂直碰撞过程进行数值仿真,获得了碰撞力、能量吸收和结构损伤变形的时序结果。为了分析船舶舷侧结构耐撞性能,对比了常见油船、新型Y型和X型舷侧结构的仿真过程,结果表明新型舷侧结构在整体的耐撞性能上优于传统的舷侧结构,承载构件的不同也会对结构的耐撞性产生很大的差异。
The non-linear dynamic analysis method is used to obtain the form of impact force, energy absorption and structural damage deformation through the simulation process between the bow and the ship side by the ANASYS/LS-DYNA software. In order to analyze the crashworthiness of ship tanker side structure, the simulation processes of the ordinary oil tanker, the new Y and the new X style ship side structure are compared. The results show that the crashworthiness of the new styles is superior to that of the traditional side structure. The different ship components have large different crashworthiness of the structure.
