摘要
随着我国海洋事业向着更深更远的领域发展,水下焊接技术在海洋资源开发、船舶工程、水利工程、钢结构的连接和服役钢结构修复等领域发挥着举足轻重的作用。由于受到水下复杂环境的限制,采用传统水下试验的方法存在成本高、工作量大、效率低等问题。因此,水下焊接有限元模拟应运而生,并受到了国内众多研究人员的青睐。针对水下焊接物理场模拟技术,阐述从单一物理场模拟到双复合物理场耦合模拟最后到多复合物理场模拟的国内外研究现状,梳理从单一物理场到多复合物理场模拟的相关方法,并对建立多复合物理场模拟模型发展趋势及必要性进行展望。
Despite that underwater welding technology has played a pivotal role in various fields such as marine resource development,ship engineering,hydraulic engineering,steel structure connections and the repair of in-service steel structures in the recent advancement of China's marine endeavors into deeper and more distant domains,it is challenged with high costs,extensive requirements and low efficiency constrained by complex underwater environments and traditional underwater testing methods.Thus finite element simulation of underwater welding having emerged as a favored approach among researchers.This paper,focusing on the simulation technology of underwater welding physical fields,summarizs the domestic and international research status from single physical field simulations to dual coupled physical field simulations and finally to multi-coupled physical field simulations,sorts out the relevant methods from single to multi-coupled physical field simulations,and envisions the development trends and necessity of establishing multi-coupled physical field simulation models.
