Abstract: The traditional experimental teaching method in shipbuilding field is difficult to meet the new trend of the development of modern shipbuilding experimental technology, the experimental means of the courses related to hydrodynamic performance of shipbuilding and Marine majors in colleges and universities are deficient at the same time. Based on the open sharing of the Internet, the ship resistance experiment teaching system based on virtual simulation is designed by using 3DMax and Unity3D. Teaching practice shows that, compared with the traditional hydrodynamic experiment teaching, this kind of experimental teaching system develops a new experimental teaching and examination mode. It integrates teaching, roaming, assessment and management, applies the concept of “internet + cloud platform” to new ship model resistance experimental teaching, combines traditional experimental teaching course. This system makes the students more clearly understand the process of the ship resistance experiment, the ability to design experiment, practice and innovation thinking was strengthened, ship model resistance experiment teaching effect is improved obviously at the same time.
