摘要/Abstract

摘要： 以厚度为0.11mm的8011-H22型铝箔为对象，利用UV打印技术对铝箔试件进行网格附着，采用曲面法开展了铝箔刚模胀形试验，由于试件本身的宽厚比很大且受到摩擦力的作用，使得铝箔在宽度方向的变形极小，所以只获得成形极限图的右半部分(次应变大于0)；同时，通过建立铝箔刚模胀形试验过程的有限元模型并结合应变加速度判据，获取成形极限图的左半部分(次应变小于0).结果表明：利用曲面法只能获取铝箔成形极限图的右半部分(次应变大于0)；而所建铝箔刚模胀形试验过程的有限元模型能够获得成形极限图的左半部分(次应变小于0).

Abstract: Thinner aluminum foil brings bigger challenge to its forming performance, so in this paper, no-damage UV printing technology was applied to marking grid in specimens, and an FLD test for 0.11 mm 8011-H22 aluminum foils was successfully launched. Because aluminum foil deformed very little in the width direction under the big width-thickness ratio and the effect of friction, only the right part of FLD could be obtained. Then the finite element simulation of rigid model bulging test was established, and the left part of FLD could be further completed based on the “strain acceleration” failure criteria. A complete FLD was then finally established.

Key words: UV printing technology, aluminum foils, forming limit diagram (FLD), strain acceleration, finite element method
