    摘要
  • 摘要: 通過圓環壓縮的有限元模擬和實驗的方法分析了金屬在高溫下變形時的摩擦邊界條件,分析了摩擦因數的大小對環形件壓縮時變形和應力的影響.通過模擬計算和實驗確定了摩擦的變化規律和金屬熱變形時摩擦因數的取值范圍.

     

    Abstract: The boundary condition of metal deformation at high temperature using experimental and FEM simulation method, and the effect of friction factor on deformation and stress of ring are studied during for-ming process. Through ring compress experiment and FEM simulation analysis, the regularity of friction can be determined and the range of friction factor in metal hot deformation can also be obtained. Maximum coulomb friction factor is around 0.4.
