Abstract: The teaching of Mechanical Dynamics is an important part of postgraduate education. In order to better stimulate the learning motivation of graduate students, improve the learning quality, and overcome the problems existing in the course, such as short class time, excessive and abstract content, and failure to closely relate to practical engineering applications, this paper proposes an exploration of teaching mode from four aspects: enriching teaching content, introducing ideological and political education, combining engineering cases, and paying attention to the overall learning effect and student interaction. Through teaching practice, graduate students'interest in the course has been significantly improved, and the teaching efficiency and quality of the course have been ameliorated.
