摘　　要：为了降低刮板输送机中部槽磨损失效而产生的影响和提高耐磨性能,综述中部槽磨损特性和耐磨优化研究的发展历程,包括磨损形式、磨损原因、磨损形貌和磨损区域等理论研究,输运条件、煤岩散料特性等试验研究,离散元法及与多体动力学耦合的仿真分析等。概括耐磨材料、表面强化技术、结构改进、仿生设计等4种提高中部槽耐磨性能的方法。提出磨损特性研究的下一步方向为磨损内在本质的研究、磨损定量的研究,提出用非线性理论方法进行中部槽磨损量拟合、磨损预测等新的研究思路;耐磨优化研究重点应在节约成本,并将耐磨技术尽快应用于刮板输送机生产实际;用非线性理论方法进行中部槽磨损量拟合预测,并从中部槽摩擦副之间的相互作用为出发点进行磨损特性和耐磨优化的研究。In order to reduce the impact caused by the wear fault in line pane of scraper conveyor and improve wear resistance,the development of wear characteristics and wear resistance optimization were reviewed,including the theoretical studies about wear forms,wear causes,wear morphology and wear areas,the experimental studies about transport conditions and coal bulk properties,and the simulation analysis about discrete element method and coupling with multi-body dynamics.Including wear-resistant materials,surface strengthening technology,structural improvement and bionic design,four methods to improve the wear resistance in line pane were summarized.It is suggested that the next direction of the research of wear characteristics is to study the intrinsic nature of wear and the quantitative study of wear.The research of wear-resistant optimization should focus on saving cost and applying wear-resistant technology to real scraper conveyor production as soon as possible.The nonlinear theory method is used to predict the wear quantity of the middle groove,and the wear characteristics and wear resistance optimization are studied from the interaction between the friction pairs of the middle groove.
