( Center for Engineering Design and Research Under the General Equipment Department,Beijing 100028, China)Abstract: Based on the originality requirement of the Beijing Olympic Games Opening Ceremony director group, the bionics folding structure system, self-balanced prestressing cable structure system and some new composite material were studied, and the technic problems of "dream earth" appear and disappear, sphere stabilization, and the weight limit of lift stage etc were resolved. The finite element calculation method for complex folding structure and its influence factor were researched. The "dream earth" in the Beijing Olympic Games Opening Ceremony has been created.
