摘　　要：　针对塑性加工过程中的轴对称变形问题,提出了一种力学计算方法,论证了圆环坐标系的坐标变换法则和主要力学方程,然后将理论计算值与实验条件下的实测值进行对比.结果表明:用圆环坐标系计算空心挤压制品的挤压力,其理论上限解准确性高.A mechanical calculation method, which was used to analyze the deformation of axial symmetry in plastic process, is put forward in this paper. The transformation rules of ring coordinate and the main mechanic equations of the deformation are discussed and then the theoretical magnitude and the measured magnitude in the process are contrasted. All these studies show that the axial symmetry can more precisely make the upper limit solutions of the force of squeezing against the hollow squeezed products.
