Optimum Design of PC Rolling Mill's Base

The optimum design method is applied in PC base in this paper.The mathematics model is given that regarded the least plus power's sum of base bounce value and frame weight as aim function,which included seven design variables and twenty*.two bind conditions and it used SUM method to calculate and get the best scheme.Compared with the previous scheme,the base weight was reduced 23.566 percent,and base bounce values were decreased 6.348 percent.
