摘要
为了能够较准确地预测某运煤专用敞车上侧梁的焊接变形,采用Sysweld系列软件对其焊接变形进行了仿真分析。其中,采用Visual Mesh 5.0模块进行了网格划分及装夹约束定义,采用Weld Planner 2009模块开展焊接变形仿真计算。结果表明,采用Weld Planner软件能够快速高效预测大型焊接构件的焊接变形;在优化的装夹约束条件下,运煤专用敝车上侧梁将产生较小的焊接变形,其两端的最大上翘变形量为3.09 mm,最大的侧弯变形量为0.156 mm,沿侧梁方向的最大收缩变形量为0.284 mm,同时,在任意2个肋板焊缝之间存在波浪变形,最大变形量为0.332 mm;模拟仿真结果可为大型复杂焊接构件的产品设计、组焊工装及组焊工艺设计提供理论参考。
In order to forecast the welding distortion of the upper side frame, welding distortion was analyzed using Sysweld simulation software. Model meshing and clamping definition were carried out using Visual Mesh 5.0. The modul Weld Planner 2009 was applied for the simulation of the welding distortion. The results showed that the prediction of large component distortion could be obtained efficiently. Minor welding distortion was achieved, with maximal warping deformation of 3.09 mm, and maximal lateral bending deformation of 0.156 mm, and maximal shrinkage deformation of 0.284 mm, and maximal wave deformation of 0.332 mm between the ribs, under optimizational clamping conditions. The simulation results could provide theoretical guidance for the product design,welding fixture design, and welding process design of large welding components.
