Based on computer simulation technology, multimedia technology, three-dimensional interactive technology and network technology, virtual simulation teaching software has established a new experimental teaching system for colleges and universities. The system restores the real scene to the maximum extent, and is no longer limited to the experimental site, equipment and materials, so that more students can participate in the experiment. For the scene experiments that are difficult, costly and destructive, they can also be vividly carried out in the virtual environment. With the help of the built-in three-dimensional lightweight browser SView independently developed by Huatian Software, students can practice experiments repeatedly, thoroughly digest and absorb each experiment, and the learning effect is doubled.

In the virtual environment, students can complete a whole set of experimental process from preview, study, practice, evaluation to report. Intuitively observe the deformation process of materials such as compression, tension and torsion, and complete the corresponding calculation according to the experimental results. Manually complete the disassembly and assembly of machine tools or parts, and carry out three-dimensional interactive operations such as movement, rotation, scaling and animation playback, and be familiar with every assembly detail, with simple operation and easy mastery. During the experiment, students can also interact with teachers and answer questions in time.

Teachers can query and review each student's experimental report, sort it according to student number, name and score, check and count the experimental results, and comprehensively supervise the teaching effect. Based on the network platform, the system can ensure the sharing of experimental teaching resources inside and outside the school, and students can also study and exchange experiments anytime and anywhere on mobile devices.

The open virtual simulation experimental teaching management and professional teaching platform have been put into use in some colleges and universities, which effectively reduces the experimental funding, obviously reduces the loss of experimental materials and greatly reduces the experimental education cost. The innovation of teaching methods shortens the time for teachers to impart knowledge and improves the teaching quality. Hands-on practice in three-dimensional scenes expands students' innovative thinking and ability.
