根据蛇形轧制的受力特点将变形区划分为5个不同的区域,分别计算了各个区域的压力分布及角位移,在此基础上运用平面应变主应力法建立了7150铝合金蛇形轧制轧板曲率的解析模型.通过蛇形轧制实验对解析模型的精确性进行了验证.使用该解析模型对蛇形轧制过程中由线性应变差引起的轧板曲率、剪切应变差引起的轧板曲率以及总的轧板曲率进行了研究.结果表明,随着错位距离的增加由剪切应变差引起的轧板曲率增加而由线性应变差引起的轧板曲率减小,它们的共同作用导致总的轧板曲率先减小后增加.随着异速比的增加,由剪切应变差引起的轧板曲率增加,由线性应变差引起的轧板曲率保持不变,它们的共同效果使总的轧板曲率增加.增大轧板初始厚度或减小压下量都会减小轧板曲率.
