| 摘 要： | 汽车覆盖件现有的面畸变评价指标均有一定的局限性,难以满足工程实践和理论研究的要求.本文分类统计了汽车覆盖件常见的面畸变分布及一般评价方法,提出了一种新的面畸变评价指标,该指标既能反映零件上各点相对标准型面曲率变化程度的几何本质,又能比较客观地评价复杂零件局部畸变的水平,并用试验验证面畸变评价指标的正确性.

| Abstract: | A new surface deflection evaluation criterion has been presented,reflecting the geometry essence that the degree of every point on parts contrasted the stamping curvature with the punch and capable of evaluating the surface deflection level of complex sheet metal stamping parts in rationality,which has been proved by experimental confirmation to be correct. |
