Abstract: Strengthening the training of engineering practical ability and engineering innovative thinking is a key direction for the cultivation of outstanding engineering talents in the new engineering mechanical major. This article combines the engineering education certification standards and the requirements of the mechanical talent training program, and based on the product development process, customizes a project-based teaching case of “design of steering trapezoidal structure for a certain off road vehicle” with practical engineering application scenarios. The content of the designed case teaching tasks is mapped to the courses and practical systems of mechanical engineering majors, with the new student mentorship system as the institutional guarantee and project-based cases as the hidden line and carrier to connect the entire process of cultivating mechanical undergraduate talents, fully stimulating students'professional self-learning initiative and enhancing their practical ability to solve complex engineering problems.

Key words: Project-based teaching cases, Engineering practical ability, Engineering innovation thinking, New engineering, Excellent engineer, Mechanical majors
