1Theoretical Analysis of the Wire Drawing Through Two Roller-Dies in Tandem显示文摘The main difference of this work from Hiroshi Nagai’sis the integral of separating force on the roller-dles. A precise equation of the contact are is proposed and used in the integral so that an analytical solution of drawing force is obtained. Thus, as a different conclusion, the new solution is in connection with the friction coefficient. The meanvalue theorem and horizontal force equilibrium are used in determining the roller-die pressure. The solutions are compared with those from Hiroshi Nagai’s.赵德文 王国栋 白光润 1993Science China Mathematics1993,36,5:1
