| 面对环件辗轧成形过程有限元计算效率极低和成形成性难以一体化调控的挑战，提出了环件辗轧智能建模仿真优化的新思路和新方法。该方法能在有限元计算过程中，实现各轧辊运动的实时协调匹配和基于目标驱动的自动调控，只需要一次有限元计算就可直接获得满足控制量（环件长大速度、轧制力、温度、组织性能等）目标要求的环轧工艺路径；简介了超大型铝合金环件(10 m级)双向辗轧智能建模仿真、超大型筒节环件轧制智能建模仿真、基于力控的大型铝合金环件（5 m级）双向辗轧工艺路径智能仿真优化、基于温控的铸坯环件双向辗轧工艺路径智能仿真优化4个方面的最新研究进展。 |
| 英文摘要: |
| To solve challenges of extremely low FE calculation efficiency and integrated control on shaping and performance, the paper proposed a new idea and method for intelligent simulation and optimization of ring rolling process. By this method, the motions of various rolls could be driven in real time during the FE analysis by the control targets of controlling variables, such as growth speed of ring, rolling force, temperature and microstructure. Thus the rolling paths obtained could directly meet the control requirements of controlling variables only by one FE calculation. Some advances in intelligent modeling and simulation of radial-axial rolling of supersized (10 m) aluminum alloy ring, supersized cylinder ring rolling, radial-axial rolling driven by rolling force of large (5 m) aluminum alloy ring, and radial-axial rolling driven by temperature of as-cast billet were introduced briefly. |
