Abstract: The reliable operation of agricultural machinery involves the construction of national food security industrial belt,  and it is very important to analyze its research status and development trend to follow up the engineering development process of agricultural machinery and equipment in time. Citespace is used to visually analyze the literature related to the reliability of agricultural machinery in China from 1980 to 2021, and the specific contents of the relevant literature are reviewed in combination with the literature research method. The results show that the reliability research of agricultural machinery in China mainly has four respects, such as reliability test, reliability analysis, reliability design and reliability evaluation. From the perspective of future development trend, the research on reliability in the field of agricultural machinery is mainly integrated with automation and informatization, and faces the diversified direction of research and development, manufacturing and service.

Key words: agricultural machinery, reliability, visual analysis, literature research method, research frontier

摘要： 农业机械的可靠运行涉及国家粮食安全产业带建设，探析其研究现状和发展趋势，对学科研究及时跟进农业装备工程化发展至关重要。运用Citespace对1980—2021年间我国农业机械可靠性相关文献进行可视化分析，并结合文献研究法对相关文献的具体内容进行述评。结果表明：我国农业机械可靠性研究主要有4个角度：可靠性试验、可靠性分析、可靠性设计、可靠性评价。从未来发展趋势来看，可靠性在农业机械领域的研究主要与自动化、信息化相融合，面向研发、制造、服务多元化方向发展。
