摘　　要：借助数值模拟技术,构建了TC4钛合金薄板激光焊对接接头有限元模型,采用热-力耦合分析的方法,对焊接过程中应力应变演变情况进行研究,获得了不同工艺参数、不同焊接方向下、不同拘束条件下的焊接残余应力和变形分布规律,为优选焊接工艺方案提供了数据支持。With the help of numerical simulation technology,a finite element model of TC4 titanium alloy thin plate laser welding butt joint was constructed.The thermal mechanical coupling analysis method was used to study the evolution of stress strain during the welding process.The distribution laws of welding residual stress and deformation under different process parameters,welding directions,and constraint were obtained,providing data support for optimizing welding process schemes.
