Abstract: Engineering practice based on virtual simulation technology is more and more widely used, especially in experimental operation. By incorporating virtual simulation technology into engineering practice, the traditional engineering practice mode can be extended to a multilevel experimental platform which combines virtual with real, and integrates theory with practice. The engineering practice platform based on virtual simulation technology is established. The contents of typical virtual simulation experiment of engineering training and its key development process are described in detail, and an engineering platform for Internet + virtual simulation is built. It overcomes many shortcomings of traditional practice platform and enriches and expands the educational concept of modern engineering practice.
