Reference (228) The course design of mechanical principle is to enable students to master and deepen the basic theories and methods of mechanical principle course comprehensively and systematically, to cultivate students' preliminary mechanical motion scheme design and analysis ability, and also to cultivate students' engineering design ability, especially the innovative design ability of mechanism system scheme.
Since the construction of top-quality courses in China started, the courses of mechanical principles in many universities have been rated as national and provincial-level top-quality courses. In the process of constructing top-quality courses, we have accumulated rich teaching experience for the practical link of mechanical principle course design. From another point of view, the research object of the course of Mechanical Principles and the concepts of mechanism and machine science are constantly expanding and developing, and the cutting-edge knowledge of the corresponding disciplines such as mechanism and robotics is also rapidly developing and constantly updating, especially the modern design theory and method for mechanism and machine system scheme design and the evaluation method of design scheme are also constantly developing and perfecting. Textbooks should reflect the latest achievements of disciplines, especially the cutting-edge knowledge of modern mechanism. This book is written to meet this need.
