Abstract: Aiming at the outstanding problems facing the engineering talents cultivation of mechanical specialty in domestic colleges and universities, this paper takes the national major strategic demand as the guidance, takes the connotation construction of mechanical specialty as the breakthrough, deepens the integration of mechanical disciplines with other disciplines, and is based on the concept of combining scientific research drive with talent cultivation.“3+1+X”bachelor-master-doctor through training mode for mechanical specialty was explored. In view of the problems such as inadaptability of research direction and undergraduate professional knowledge, repetition of courses or teaching contents, improper connection of training links or courses to a certain extent, insufficient knowledge breadth and depth, etc., which bachelor-master-doctor has trained in all stages of“4+3+3”, combining the characteristics and discipline advantages of mechanical specialty, taking into account such links as theoretical courses, experimental courses, practice base training and international exchange, teaching and scientific research forces are optimized. The implementation path of the interdisciplinary and longitudinal progressive integrated course of mechanical specialty, undergraduate, postgraduate and doctoral degree has been constructed, which provides beneficial exploration for the reform of the pass-through talent training mode.
