摘要
从舰船结构强度分析领域的实际工程需要出发,指出舰船结构性能快速评估的作用与意义,结合多种计算机辅助结构设计软件,探讨基于数值仿真的舰船结构性能快速评估方法,同时搭建初步的快速评估系统框架。舰船结构碰撞损伤实例分析表明,该快速评估系统可以同步快速分析各种碰撞损伤以及对应损伤状态下的结构剩余强度,体现出基于结构性能快速评估技术的数值仿真方法在舰船损伤剩余强度评估领域的优势。
As the requirement that actual project needs analyzing ship structural strength,we found that it is so necessary to do fast assessment for naval vessel structural properties.So based on numerical simulations by multiple kinds of computer aided softwares,we probed into the method of fast assessment and established a preliminary framework with the combination of a variety of CAE software.Ship collision damage analysis in this paper,for example,demonstrated the feasibility of this fast assessment system,which could sync quickly analyze all kinds of collision damage and corresponding damaged structural residual strength.All reflect the advantages of numerical simulation method,which based on fast assessment of structure,in the field of damaged ship＇s residual strength evaluation.
