型砧锻造圆坯连续速度场的上界解析解

An Upper-bound Analytic Solution to Shape-anvil Forging of Rounds with Continuous Velocity Field

建立了型砧锻造圆坯满足运动许可条件的连续速度场与应变速率场,后由上界定理,求得上界解析解,该解与传统工程法的结果进行了比较。

A kinematic admissible continuous velocity and strain rate fields for shape-anvil forging of rounds with counter locked die are established. An analytic solution is obtained by the upper-bound theorem. Then the solution is compared with that by traditional slab method.
