摘要:
采用斜面冲头和斜端面橡胶为介质,非线性显式动力分析软件ANSYS/LS-DYNA为数值模拟平台,建立三通管复合胀形的有限元模型,并研究斜面冲头、普通冲头、斜端面橡胶棒及垂直端面橡胶棒对三通管件成形质量的影响.结果表明:随着轴向斜冲头斜度增加,管件壁厚减薄率是先减小后增大,增厚率逐渐减小;随着橡胶斜度的增加,三通管件支管高度是先增加后减小.因此,当冲头斜度α=10°时,三通管的成形质量最佳;当冲头斜面和橡胶斜面同为8°时,壁厚减薄率控制在11%,则成形支管高度最高为16.37 mm.
Abstract:
Using slope punches and inclined rubber stick as medium, and nonlinear explicit dynamic analysis software ANSYS/LS-DYNA as numerical simulation platform, a finite element model of the T-shapes tube composite bulging is established in this paper. The bevel punches and ordinary punches, oblique end rubber and the vertical end rubber is compared to study forming quality of T-shapes tube. The results indicate that with the slope punch oblique α increases, the tube wall thinning rate is decreased firstly and then increased, the thickening rate is gradually decreased. With the rubber oblique increases, the tube’s height is increased firstly and then decreased. Therefore, when the punch angle α=10°, the forming quality of T-shapes tube is best. When the punch obliquity and rubber obliquity are 8° simultaneously, and the tube wall thinning rate is controlled in 11%, the maximum height of forming branch height is 16.37 mm.
