In recent years, with the proposal and implementation of the intelligent manufacturing strategy, mechanical engineering control theory has become the core support for the intelligent upgrading of equipment. However, as a core course for mechanical majors, “Fundamentals of Mechanical Engineering Control” features a strong theoretical and abstract nature. The traditional teaching mode easily leads to difficulties in students’ understanding and insufficient learning interest. “Knowledge visualization” can present the abstract knowledge in the course in visual forms such as graphics, images, and animations, helping students better understand and master the course content, thereby fully stimulating their learning interest, improving their learning effects, and effectively cultivating their innovative and practical abilities. In this regard, this paper first expounds on the significance of the teaching reform of the course “Fundamentals of Mechanical Engineering Control” based on the theory of “Knowledge Visualization”, and then proposes effective reform strategies, aiming to provide certain references for relevant researchers.
