摘要
在基于有限元数值模拟的基础上提出了反向最小余量法,用以优化芯辊进给速度曲线。优化后的芯辊进给速度曲线能保证辗扩过程中始终有理想的每转压下量,从而降低缺陷的发生,提高零件质量。最后结合具体零件进行了数值模拟验证,验证结果理想。
A new method,which named reverse shrinking surplus method,has been pointed out based on the FEM in order to optimize the speed curve of the spindle.The optimized speed curve can bring a steady press-down dimension in the process of the ring rolling which could assure high quality products.At last a specified product has been selected to validate the method, which implies that the method is advisable.
