摘　　要：传统的压边力计算公式由于考虑的因素较少,因而精度较低。利用数值模拟技术和响应面法,建立筒形件最佳压边力与板料几何参数、材料性能参数和模具几何参数之间的关系函数。根据所得的关系函数,针对具体的材料、板料和模具,可以快速计算出相应的最佳压边力,以达到成形质量提高的最佳效果。The traditional blank holder force formula, considered less factors,resulted in low exactness. By using numerical simulation technology and the response surface method, this paper established a relation function of cylindrical optimum blank holder force, this function combined blank holder force with sheet metal geometry parameters, material performance parameters and mould geometric parameter. With the relation function, the best blank holder force which will achieve the best effect can be quickly calculated according to specific materials, sheet metal and mould performance parameters.
