Abstract: In order to broaden students’ engineering vision and develop their ability to solve engineering problems, this paper designs an experimental teaching device for measuring the coordinates of the gravity center of objects. This device meets the needs of the marine, automobile, machinery, and other industries to determine the position of the gravity center of objects, and also takes into account the characteristics of relevant majors of Dalian University of Technology. The teaching device is stable and easy to operate, and the experimental results are consistent with the theoretical calculation values. The teaching application of the equipment enrich and improve the teaching content of basic mechanics experiments, and achieve good teaching results.
