由于爆炸焊接工艺过程的特殊性,大幅板爆炸焊接中存在的结合面焊接缺陷问题产生的原因一直未能得到明确揭示,论文利用非线性动力数值模拟,考察了3.5m-7.0m钛钢大幅板爆炸焊接质量问题产生的原因,发现大幅板爆炸焊接过程中复板存在褶皱变形现象,指出褶皱变形的出现与所用板幅尺寸比例密切相关,随着板幅尺寸比例的变化,褶皱变形持续时间、影响范围置以及最大褶皱深度存在规律性变化.
Due to the particularity of the explosion welding process, the reasons for the welding flaw in the welding of the large-size plate have not been clearly revealed. The nonlinear dynamic numerical simulation is used to investigate the effects of the 3.5m-7.0m large-size titanium steel plate It is found that there is a wrinkle deformation in the composite plate in the process of explosive welding. It is pointed out that the appearance of the wrinkle deformation is closely related to the proportion of the size of the plate used. With the variation of the proportion of the width, the duration of wrinkle deformation, The influence range and the maximum fold depth have regular changes.
