With　the　development　of　intelligent　manufacturing,　simulation　technology　has　become　one　of　the　important　research　of　industrial　simulation　systems.　This　paper　proposes　a　method　for　realizing　a　industrial　simulation　system　based　on　the　BIM　technology　and　the　functional　mock-up　unit　(FMU),　which　can　be　applied　to　many　industrial　fields.　We　analyze　various　methods　of　loading　three-dimensional　models　by　OpenGL,　and　provide　the　specific　implementation　process　and　technical　points.What＇　more,　we　realize　the　interactive　operation　of　three-dimensional　model　through　programming.　Finally,　we　propose　a　method　for　information　exchange　between　FMU　and　simulation　system.　As　a　result,　data　simulation　and　virtual　simulation　of　3D　scenes　are　all　realized.
