【摘要】 汽车覆盖件冲压成型的变形分析与受力分析是冲压工艺设计和模具设计的基础。在分析基本形状零件冲压成型的变形特点的基础上,提出了汽车覆盖件冲压变形分析的“微分思想”,即利用“微分”原理首先对零件的各个局部进行变形分析,然后将各个局部的变形进行“积分”。更多还原

【Abstract】 Analysis of deformation and forces in stamping and forming automotive covering parts is the foundation of their process planning and diede sign. Based on the analysis of deformation characteristics in stamping and forming typically shaped parts, a concept of "differentiation" is introduced for studying the deformation in stamping operation, i. e. firstly the deformation in each partial element of the part is analysed by the concept of differentiation, then the deformation in each the partial element can be "integrated".更多还原
