摘要

本文对飞机机身T型接头结构的双激光双向同步焊接（DLBSW）进行了数值研究。为了获得由6156铝合金蒙皮和6056铝合金桁条组成的民用飞机壁板焊接参数的合适匹配，对DLBSW进行了有限元数值模拟。对飞机壁板焊接残余应力和焊接变形的分布进行了预测和讨论。建立了含有三个桁条的面板的三维有限元模型，模拟了温度场、残余应力分布和焊接面板变形。模拟了三根桁条通过不同的焊接顺序焊接到试件底板上，得到了变形最小的焊接顺序。

The deformation and residual stress simulation of dual laser-beam bilateral synchronous welding for Al-alloy aircraft panel structure

This paper reports a numerical investigation of dual laser-beam bilateral synchronous welding (DLBSW) for T-joint structure of aircraft fuselage. Finite element numerical simulation of DLBSW is carried out to obtain suitable matching of welding parameters for civil aircraft panels which composed of 6156 aluminium alloy skin and 6056 aluminium alloy stringer. The distribution of welding residual stress and welding distortion on the aircraft panels are predicted and discussed. Three-dimensional finite element model of the panel containing three stringers has been developed to simulate the temperature field, residual stress distribution and welded panel distortion. It is simulated that three stringers are welded to base plate of the specimen through different welding sequences and the welding sequence with the smallest distortion is acquired.
