双联齿轮、双面法兰等小孔深槽环形零件在各种工程机械中应用广泛。三辊斜轧是一种加工小孔深槽环件的先进塑性成形新技术。本文在ABAQUS软件环境下建立了小孔深槽钢领TRCR的三维热力耦合有限元模型。通过模拟分析，揭示了成形过程中应变和温度的演化和分布规律，探索了关键工艺参数对变形均匀性的影响。研究结果为工艺参数的设计和优化提供了有价值的指导。
Ring parts with small-hole and deep groove such as duplicate gear and double-side flange, are widely used in various engineering machineries. Three-roll cross rolling (TRCR) is a new advanced plastic forming technology for the processing of rings with small-hole and deep groove. In this paper, a 3D coupled thermo-mechanical FE model for TRCR of ring with small-hole and deep groove is established under ABAQUS software environment. By simulation and analysis, the evolution and distribution laws of strain and temperature in the forming process are revealed, and the effects of the key process parameters on the deformation uniformity are explored. The results provide valuable guideline for the technological parameter design and optimization.
