中文摘要:
      回转窑支承系统的对中性是其长期安全稳定运行的核心保障。针对传统依赖人工经验调整存在的精度低、滞后性强的问题，本文基于弹性力学与连续梁理论，构建了多支承回转窑的“等载同轴”理想力学模型，并深入剖析了不对中故障的非线性演化机理，提出了一种融合多源异构数据感知、基于专家规则与优化算法的智能化调整策略。通过建立“感知-诊断-决策-执行”的闭环控制体系，实现了调整过程的量化与精准化。工程应用表明，该策略能有效将窑体中心线偏差控制在3 mm以内，各档位载荷不均问题改善超过75%，为实现从“经验驱动”到“数据驱动”的精准运维提供了理论方法与工程实践路径，对提升设备可靠性、降低维护成本具有重要意义。
英文摘要:
      The alignment of the rotary kiln support system is the core guarantee for its long-term safe and stable operation. In view of the problems of low accuracy and strong hysteresis existing in traditional manual experience-based adjustments， this paper constructs an ideal mechanical model of "equal load and coaxiality" for multi-support rotary kilns based on elastic mechanics and continuous beam theory， and deeply analyzes the nonlinear evolution mechanism of misalignment faults. An intelligent adjustment strategy that integrates multi-source heterogeneous data perception， expert rules， and optimization algorithms is proposed. By establishing a closed-loop control system of "perception-diagnosis-decision-execution"， the quantification and precision of the adjustment process are achieved. Engineering applications show that this strategy can effectively control the kiln body centerline deviation within 30mm and improve the uneven load problem at each gear position by more than 75%. It provides a systematic theoretical method and engineering practice path for achieving precise operation and maintenance from "experience-driven" to "data-driven"， which is of great significance for improving equipment reliability and reducing maintenance costs.
