仿真技术在铝制发动机罩焊接工艺中的应用

Application of Simulation Technique in Welding Process of Aluminium Engine Hood

为加快铝制发动机罩导入进程,利用数值模拟和全球制造模拟(GMS)验证焊接机器人的可达性、干涉性和生产节拍的保障能力,并通过数值模拟确认发动机罩焊接变形量满足工艺要求,实现与生产线、工装夹具的并行工程,加速导入工装夹具,最终实现车型导入周期缩短3个月,成本降低约20万元,同时提高了焊接质量。

In order to speed up the process of introducing aluminum engine hood,numerical simulation and Global Manufacturing Simulation(GMS)are used to verify the accessibility,interference,production cycle of the welding robot,and numerical simulation is used to confirm that the welding deformation can satisfy the process requirements,realize parallel engineering with production line,tooling and fixture,and accelerate the introduction of tooling and fixtures.Finally,the introduction cycle of models can be shortened by 3 months,cost reduction of 200,000 RMB,with improved welding quality.
