基复板间距对钛-不锈钢爆炸焊接质量影响的数值模拟
Numerical Simulation of Stand-Off Distance Effects on Explosive Welding Quality of Titanium-Stainless Steel
摘要
Abstract
The effects of stand-off distance on explosive welding quality between titanium(TP 270C)and stain-less steel(SUS 821L1)composite plates,were investigated.The 3D numerical simulations were conducted with the ANSYS/LS-DYNA software by 2 algorithms(the ALE method and the SPH-FEM coupling method)for 3 stand-off distances:1.2 mm,2.2 mm and 3.5 mm.The simulation results show that,for both algorithms the vertical displacements of flyer plates reach or exceed respective stand-off distances.The collision velocities and angles consistently fall within the acceptable range of the welding window.The collision velocity and angle ex-hibit positive correlations with increasing stand-off distances.Optimal welding quality occurs at the 3.5 mum stand-off distance.The results verify that both algorithms effectively simulate explosive welding between the TP 270C titanium alloy and the SUS 821L1 stainless steel.Stable bonding is achievable across all tested stand-off distances.Moreover,the interfacial bonding strength increases progressively with the stand-off distance,which demonstrates an enhancement mechanism in welding quality through parameter optimization.关键词
