汽车覆盖件破裂试验及基于广义成形技术仿真（Experiment of Auto Panel Surface Fracture and Simulation Base on Universal Formability Technology）
汽车A表面 破裂缺陷试验 广义成形技术
2009/11/24
针对汽车外覆盖件的A级表面，设计并制造了4种不同试验模具，在试验模具中包含了在汽车外覆盖件容易产生破裂的典型的反拉延特征。通过冲压试验，观察到表面破裂缺陷的产生，并搜集产生表面破裂缺陷处的应变及位移的历程及在破裂区域的接触压力的数据。同时，以自主开发的商品化冲压成形CAE软件KMAS/UFT模块为平台，针对冲压过程中破裂缺陷进行精确预示，并以CAE数值模拟软件LS-DYNA3D对比，模拟计算结果与...
