The virtual reality of rapid expansion mechanism motion simulation and virtual assembly research can improve the structure optimization of rapid expansion mechanisms and assembly proces efficiency, and reduce development costs. A NC shield fast movement retractable mechanism basic model was established by means of Solidworks, then it used 3DMAX and Multigen creator software for model transformation. The faces were streamed and optimized under the principle of mechanism and software optimization. The mechanism movement freedom model was finally established combined intersecting lines and double dof dots, which realized the requirements of virtual reality simulation system for fast movement retractable mechanism model. Research on structure and assembly process by means of virtual reality using the model that it established though above can improve R＆D productivity effectively.
