T型管液壓成形過程的有限元分析

Analysis of T-shaped Tube Hydroforming by Finite Element Method

  • 摘要: 應用動態顯式有限元法,建立了T型管液壓成形分析模型,對不同加載條件下的模擬結果進行對比,分析了軸向載荷的作用,探討了最佳載荷曲線的確立原則.

     

    Abstract: Workpiece forming in the T-shaped tube hydroforming process takes place through internal pressure and axial load. If these loads are chosen poorly there will be failure in the workpiece involving wrinkle or bursting. A dynamic FEM model is built for the T-shaped tube hydroforming process. Through analyzing the different simulation results, the influence of axial load is discussed and the optimum loading profile is determined.
