This paper mainly presents the pedestal architecture of Three-axis Virtual Flight Motion Simulator. During the system, it places emphasis on such modern technique as PDM/CAD/CAE, data engine, virtual assemble & virtual prototyping (VP), and discusses about the work style and mechanism of Virtual Flight Motion Simulator. As for running mechanism, the system, based on PDM, efficiently designs mechanical structure and manages both drawings and producing process. It also realizes dynamic assembling of models using two techniques between OpenGL and virtual assembling tool. The virtual system primarily mimics many characters of the real flight simulator and implements the comprehensive analysis between mechanical system and control system based on VP by adjusting and optimally designing mechanical structures and control methods, developing time of real simulator system is accelerated.
