Modern applied mechanics research has developed toward multidisciplinary cross discovery, and numerous branch courses have appeared in applied mechanics teaching, different courses are taught by using different methods, and the connection between them is less talked about in teaching. It is difficult for students to integrate the knowledge of different courses in a limited time, and the learning burden is increased while the academic vision and independent thinking ability are weakened. To this end, this paper studies a new model of applied mechanics teaching from the perspective of integrating teaching reform, science popularization and ideology and politics, and summarizes relevant practical teaching experience. This study can also provide useful reference for other engineering courses teaching.
