In order to achieve the performance of lunar rover simulation assessment in a variety of state of motion, based on programming in the Pro/E modeling environment, 3-D terrain profile and vehicle models were changed to SQlite database directly. Lunar rover dynamic model was set up with Vortex’s API functions. And then, visualized objects can be rendered by using OSG graphic engine. The typical terrain mechanical models in Vortex were evaluated and fixed based on wheel soil bench tests. Finally, 3-D visualized software was developed with Microsoft MFC framework, which had function of interrupt, call-back and simulation’s datum recurring.
