樹脂復合輕質夾層鋼板彎曲成形性的數值模擬

FEM Simulation on Bending Formability of Resin Composite Lightweight Steel Sheets

  • 摘要: 利用ANSYS有限元軟件模擬分析了樹脂復合輕質極的彎曲成形性能.輕質板是夾層板,彎曲過程中,外層鋼板易產生相對錯動量.因此對輕質板內部的應力應變狀態進行分析,研究模具參數和板料的復合結構以及中間層樹脂的材料參數對錯動量的影響,同時對彎曲后的回彈和剪切應力的情況進行了分析.

     

    Abstract: The ANSYS simulation software has been used to analyze the bending formability of resin composite lightweight steel sheet. Because the lightweight steel sheet is composite, the outside steel sheet produces relative slipping-off change during the bending. So the inner stress-strain situation, the effect of material parameters and tool parameters, composite structure and intermediate-layer resin of lightweight sheet on slippingoff change have been analyzed. At the same time, the spring-back and searin stress situation after bending have been discussed also.
