| 摘 要： | 由于大型锥形筒节存在锥度，考虑金属沿锥向的流动，首先采用微分分层计算法和切块法建立了大型锥形筒节轧制力力学模型；然后基于ABAQUS有限元软件，建立了大型锥形筒节轧制过程仿真模型。模型计算结果和有限元仿真结果表明：力学模型计算轧制力与有限元计算总轧制力的相对误差在20%以内。对比分析了力学模型和有限元模拟计算单位轧制力的分布。通过分析芯辊和外辊的转速比，得出了所建力学模型的稳定轧制的适用范围。

| Abstract: | Considering the conical metal flow due to the conicity of large conical cylinders, the mechanical models of rolling force for large conical cylinders were established based on differential layered calculation method and slicing method ,and then the finite element models of the rolling processes for large conical cylinders were performed using the ABAQUS software. The results of model calculation and finite element simulation show that the relative errors of rolling forces between mechanics models and finite element models are less than 20%. The distribution of unit rolling force between model calculation and finite element simulation is compared and analyzed afterwards. Finally, the application scopes of the mechanics model established for stable rolling are obtained by analyzing the speed ratio of core roller to outer roller. |
