摘要拉深成形是加工薄壁开口空心零件的典型方法，在冲压加工的实际生产中占有重要的地位。在三棱盒的冲压成形过程中，破裂和起皱现象最为严重，也是最容易发生的缺陷，通过对三棱盒拉深成形的有限元数值模拟分析，可以改善形件的表面成形的质量，控制板料在拉深成形过程中的缺陷的产生。25385
本文给出了三棱盒拉深成形研究背景和意义, 对三棱盒形件拉深变形的主要特点进行了定性分析，研究了三棱盒拉深成形的主要缺陷。利用solidworks进行前期的模具建模，然后通过Dynaform这一有限元分析软件进行三棱盒拉深成形的仿真分析，并进一步分析了压边力、模具参数、板料参数等因素对三棱盒拉深成形的影响，提出了正交试验与参数分析方法，以得出最佳参数组合方案。并参考性的提出该课题的研究方向和研究方法，为探讨非对称的复杂拉深盒件冲压成形工艺打下基础。

Title Finite Element Analysis And Process Research Of Magnesium Alloy Triangular Box Deep Drawing.
Abstract
Deep drawing is a typical method of processing open thin-walled hollow parts, and it plays an important role in the actual production of stamping. The cracking and wrinkling is the most serious phenomenon in the process of stamping of triangular box, and it is the most prone to defects. The surface quality of the parts can be improved and the cracking and wrinkling defects can be controlled by finite element simulation analysis of the triangular box deep drawing.
In this paper, the background and significance of the triangular box deep drawing ware given, the main features of the rectangular box drawing deformation ware analyzed, and the major defects of the triangular box deep drawing ware researched.First of all, the stamping mould was modeled by solidworks. Then Simulation analysis of deep drawing was simulated by finite element analysis software Dynaform .The influence of BHF, mould parameters and sheet parameters and other factors on the triangular box deep drawing was analyzed, The orthogonal test and parameter analysis was proposed, and the optimal parameters combination was found, which laid the foundation of discussion the stamping process of asymmetrical complex rectangular box.
Keywords Triangular box deep drawing Univariate analysis Orthogonal Test
