摘　　要：以悬臂梁自由端受集中载荷为模型,研究动臂焊后变形矫正过程,分析了动臂矫正时动臂板的位置变化和各变形量之间的关系、弹性小挠度变形时载荷和变形量的关系、发生塑性大挠度变形时载荷和变形量的关系、卸载回弹时载荷和变形量的关系,分析了影响矫正距离的因素,为寻找合适的动臂矫正距离提供支撑。Taking the process of loader arm after welding deformation of mechanical as the model of free end of thecantilever beam under concentrated load in this paper, analyzes the loader arm plate position changes and the deformation and the relationship between the elastic deflection in elastic deflection process, plastic deflection process, unloading load and deformation process. Analyzed the influence factors of distance correction, to find appropriatecorrective distance.
