摘　　要：针对目前拉弯矫直过程缺少完整的数学求解模型的问题,根据矫直带材在拉弯过程中,中性层偏移量及延伸率的计算模型,给出了拉弯矫直张力、矫直力和延伸率的计算方法。通过计算与工业试验,分析了拉弯矫直机矫直规程对残余延伸率的影响,并验证了计算模型的精确性。At present, there was a lack of complete mathematical model in process of stretch-bend straightening. According to the calculation models of the neutral layer offset and the elongation of the strip in the process of stretch-bend straightening, the calculating methods of the tension, straightening force and elon- gation were given. Through calculations and industrial tests, the effects of the straightening procedure on the residual elongation were analyzed, and the accuracy of the models was verified.
