Abstract:
      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.
