面向船体分段吊装工艺的多功能设计系统开发
Development of multi-functional integrated design system for ship block lifting process
摘要
Abstract
Based on the discrete data extracted from ship block AM(AVEVA Marine)model,along with triangulation data,lifting process information,lifting equipment information,an optimization algorithm was proposed for ship block lifting points layout.Using the highly reliable AFT-Delaunay(automatic finite element-delaunay)surface mesh generation algorithm,and a finite element analysis framework including control algorithm,unit calculation and constitutive calculation extension interface,a multi-functional integrated design system for block lifting process was developed.This system provided automated solutions for solving the problems of automatic solution of lifting points layout,dynamic simulation of ship block lifting process,mesh division of lifting lugs and automatic finite element calculation.Finally,taking the bilge block of a crude oil ship as an example,a comparison between the commercial finite element software MSC.NATRAN and this system in terms of finite element calculation results,mesh generation and finite element visualization was made,demonstrating that the system achieves a comparable level to commercial finite element software in terms of ship block lifting safety evaluation.关键词
