摘要
采用极值原理的功能平衡法．确定挤压变形区内金属的位移增量，并依此建立挤压力计算模型。此方法供工程设计参考。
In the paper, the incremental function of strain and displacement of themetallic deformation region can be defined by the functional equilibrium method of extremum principle when workpiece is extruded through the cone mould. On the base ofthe incremental fanction, a calculation formula of extruding pressure is obtained bymeans of the principle of energy balance. This formula is available to the engineeringpractice.
