中文摘要：以典型覆盖件汽车后尾安装支架T/LP为研究对象，总结了汽车后尾安装支架的结构特点和性能要求，并利用AutoForm软件对某车型的后尾安装支架的拉深成形过程进行了模拟，预测板料成形过程中减薄、拉裂、起皱等缺陷，同时分析缺陷产生的原因，进而优化板料成形工艺参数和改进模具结构。
英文摘要：The automobile covering panel bracket-T/LP was taken as study object, the structure characteristics and function request were summarized. The drawing process for bracket-T/LP was numerically simulated by AutoForm software. The defects like thinning, fracture and wrinkling in the process of sheet metal forming were predicted and the causes were investigated. Furthermore, the processing parameters were optimized and the die structure was modified.
