摘要

摘要: 采用不同凹模圆角半径下的圆筒拉深实验,对热镀锌钢板DC53D+Z和合金化热镀锌钢板DC53D+ZF拉深成形工件表面损伤行为进行研究。实验结果表明,在不同凹模圆角半径下,DC53D+Z 表面损伤有熨平纹和表面划痕两种形式,而DC53D+ZF的表面损伤则有镀层龟裂和表面划痕两种形式;随着凹模圆角半径的减小,DC53D+Z熨平纹现象增加,DC53D+ZF垂直拉深方向的裂纹增加。利用ANSYS/LS-DYNA有限元分析软件,建立基于界面结合的镀锌板圆筒拉深有限元模型,对镀锌钢板拉深过程进行模拟。模拟结果表明,随着凹模圆角半径的减小,镀层沿拉深方向的第一主应变增加。数值模拟结果与实验结果对比表明,镀层沿拉深方向的第一主应变是影响表面损伤程度的主要原因。

Abstract: The surface damage behavior in the cylinder deep drawing of hot-dip galvanized steel(DC53D+Z) and hot-dip galvannealed steel(DC53D+ZF) under the different die radius were investigated. The experimental results indicate that ironing signs and scratching are two kinds of surface damage for hot-dip galvanized steel, coating cracking and scratching are two kinds of surface damage for hot-dip galvannealed steel. The ironing signs of the DC53D+Z and the cracking of the DC53D+ZF coating obviously increases with the decreasing of die radius. The finite element model for cylinder drawing of galvanized sheet with an interface composite was established via ANSYS/LS-DYNA software. The simulation results show that the maximum principal strain along the drawing direction of coating increases with the decreasing of die radius. The maximum principal strain along the drawing direction of coating may be the main reason affecting the level of surface damage.
