Under the background of digital transformation of college education, how to make good use of virtual simulation experiment teaching course resources is an urgent problem for all colleges and universities. This paper analyzes the problems faced in the course resource sharing process of virtual simulation experiment teaching. The architecture and function modules of the virtual simulation experiment teaching resource sharing platform based on the digital technology are researched and designed following the principles of system connectivity, efficient collaboration, resource integration, technical support, step-by-step construction and continuous expansion. The platform contains a rich library of experimental teaching courses, realizes the docking with the personnel and educational administration management system, and introduces a big data analysis technology, which not only meets the personalized learning needs of students, but also helps teachers continuously improve the quality of teaching.
