中文摘要:
      为促进铝合金板材在脉冲电磁力作用下调形方法的工艺化,研制了调形设备,满足了规格小于等于1500mm×800mm×6mm的试件调形要求。基于此设备,研究了电磁力调形道次对2198-T3铝合金试件形貌和曲率半径的影响。采用平面螺旋电磁线圈对试件进行不同道次的调形试验,结果显示原始平直状态的试件经过调形后呈现出双曲率的曲面特征。随着调形道次的增加,试件曲率半径减小,弯曲变形量增大,其变形量随调形道次的增加而趋于饱和。

英文摘要:
      In order to promote the shape adjustment method of aluminum alloy sheet using pulsed electromagnetic force to a mature process. An appropriative equipment was developed, which can satisfy the shape adjustment of sheets not larger than 1500mm×800mm×6mm. The effect of shape adjustment times on the shape and curvature radius of 2198-T3 aluminum alloy specimens were studied based on that equipment. A flat spiral coil was used to conduct the shape adjustment experiments of specimens in different action times of pulsed electromagnetic force. The results show that the original flat specimens present double curvature surface features after shape adjustment. Curvature radius decreases with the increase of shape adjustment times while deflection increases with it and reaches a saturation value.
