基于固有应变法原理,利用计算机仿真技术对某大型焊接件进行焊接装配数值仿真分析。对比分析了加筋板与不加筋板的变形与应力区别,确定了焊接筋板施加位置对大型构件焊接最终结果的影响,控制了工件焊接质量,为实际生产提供理论依据。
Based on the principle of inherent strain method, the numerical simulation analysis of a large welding part is carried out by using computer simulation technology. The difference between the deformation and the stress of the stiffened plate and the non-stiffened plate is compared and analyzed. The influence of the welding rib applied position on the final welding result of the large component is determined. The welding quality of the workpiece is controlled and the theoretical basis for the actual production is provided.
