摘　　要：分析了棒材无模拉伸的变形模型及速度场，采用上限法确定了棒材无模拉伸力能参数计算公式，并从理论上分析了棒材无模拉伸力能参数的影响因素及影响规律．经过实验证明，理论计算结果与实验结果相吻合．On the basis of analysis in deformation model and velocity field during rod dieless drawing,the calculating formula of drawing force has been determined by means of upper boundary method.The influence factors and laws on dieless drawing force parameter are also analysed theoretically.According to experimental study,the theoretical calculating results of drawing force are much approximate to that of experiment.
