Welding distortion control of ship structure is a vital component of precision shipbuilding.It is significant to improve ship quality and to shorten building period.Process of research and application on prediction and control welding distortion of ship structure is reported.Various numerical simulation methods and features about prediction welding distortion have been discussed.The anticipation of thermo-elastic-plasticity finite element method and inherent strain method in shipbuilding has been represented detailed.Measures of control welding distortion have also given.Thus,precision shipbuilding technology could be promoted in shipyards.

从本质上讲,虚拟仿真是一种计算机技术用来定义如下内容所需的所有步骤,包括构建船舶产品(结构装配、安装发动机、分段组装、管道折弯等),完整性测试,提供制造设备与生成工作指令.

引言 现代造船要求速度,质量和成本,影响这三个因素的是船舶设计和制造阶段的工作.虚拟仿真技术使得制造人员能够影响设计,从而减少制造成本以及消除由于设计问题影响建造而造成的工程修改.
