爆炸焊接三维数值模拟

Three dimensional numerical simulation for explosive welding

  • 摘要: 采用非线性有限元软件MSC.Dytran对爆炸焊接过程进行了三维数值模拟,获得了爆炸焊接过程中速度及界面压力的分布及其大小,并与经验公式的理论计算结果进行了比较。结果表明,爆炸焊接数值模拟的结果与理论计算值基本相符,所建数值模型准确,Dytran可较好的模拟爆炸焊接过程,计算爆炸焊接过程中的压力及速度变化分布,但不能对爆炸焊接过程中的射流及波形特征进行模拟。通过三维数值模拟可方便地了解爆炸焊接过程,对爆炸焊接工艺参数的选择提供参考。
    Abstract: Explosive welding process was numerically simulated with 3D by nonlinear finite element softwareMSC.Dytran.Velocity and pressure distribution were also calculated during explosive welding process.The numerically simulated results were compared with theoreticaly calculated results, which showed that the numerically simulated results were much similar with theoretic results.The results indicates that the mathematical model can be exactly to simulate explosive welding.Velocity and pressure distribution during explosive welding process can be simulated simply by Dytran.However, it can' t simulate the formation of jet and wave-form in explosive welding.The simulation can be referred to explosive welding technology.
