"Fundamentals of Mechanical Design" is aimed at mechanical and non-mechanical engineering students, and adopts an all-English teaching mode. The course systematically integrates the core contents of mechanical principles, mechanical design, interchangeability and measurement technology, material mechanics, etc., combined with modern design methods and engineering cases, and sets up a total of 24 hours of theoretical teaching. The course selects the international classic textbook "Fundamentals of Machinery Design", and the teaching content covers knowledge modules such as mechanism motion analysis, strength calculation of mechanical parts, application of tolerance matching standards, and evaluation of mechanical properties of materials, focusing on interdisciplinary ability training, which not only lays a solid design foundation for mechanical students, but also helps students majoring in automation and vehicle engineering to build mechanical system cognition.
