| Abstract: | In view of the lack of experiment equipment and place, analyzing the current condition and features of virtual labs. On the basis of studying the process, method and related technology of constructing 3D interactive virtual scene with Cult3D, taking the gear reducer as example, a gear reducer virtual disassembly and assembly experiment is constructed with Cult3D and other related software tools. The virtual experiment system is proved to be of good efficiency in practical application owing to its characters of three-dimension，dynamic, interaction, low-bandwidth transmission, and overcoming the discomfort of traditional experiment. |
