摘　　要：用三维有限元接触计算方法分析了大型锻造液压机全预紧机架的整体工作性能,较为确切地计算了各部件的变形及彼此间的接触内力分布,并给出了梁-柱结合面缝隙的具体形态。在此基础上确定了预紧参数。Through 3-D FEM contact algorithm, the overall working performance of fully pretightened frame for large hydraulic forging press is analyzed; basically deformation and contact stress distribution are accurately calculated. Furthermore, the concrete shapes of combination surfaces between columns and beams are presente ＆ Based on all these results, pretension parameters are decided.
