摘　　要：通过分析伺服驱动辊锻机的工作原理和结构特点,用建模软件搭建三维模型,采用整体施加载荷、各零件单独分析的静力学分析方法,利用仿真软件模拟250 mm伺服驱动辊锻机整体模型在四道次辊锻受到最大辊锻力250 k N时、锻辊在高度方向的变形及受到的应力情况。结果显示:在锻辊四道次变形中,第2道次为最大变形道次,上下锻辊变形之和为0.60991 mm,计算出其刚度为409 k N·mm^(-1),而辊锻机的许用刚度Ch为350~500 k N·mm^(-1),符合刚度标准;在锻辊四道次应力值强度分析中,第4道次Von-Mises应力值最大,有效值达到63.267 MPa,小于辊锻机的许用应力326.8 MPa,完全满足应力值强度的要求,由结果可知,250 mm伺服驱动辊锻机锻辊的刚度强度完全满足要求。By analyzing the working principle and the structure characteristics of servo drive forging press,a 3D model was built by modeling software. When the maximal roll forging force of 250 kN was applied to forging roll in the process of four passes respectively,the deformation of forging roll along the height direction and the stress in the 250 mm servo drive forging press model were simulated by software adopting static analysis method through applying overall load and analyzing components. The results show that in the four passes deformation,the second pass deformation is the largest with the sum value of upper and lower forging roll deformation 0. 60991 mm. The stiffness is calculated as 409 k N·mm^-1,and the admissible rigidity Chis 350-500 k N·mm^-1,so the rigidity standard is met. Furthermore,in the four passes stress analysis,the fourth pass Von-Mises value is the largest as 63. 267 MPa which is less than the permissible stress326. 8 MPa and meets the stress requirement. Based on the above results,the stiffness and strength of the 250 mm servo drive forging press fully meet the actual requirements.
