The sunshade is a device for relieving the global warming. On this basis, the huge space shield is put forward. It means that a large shield surface is placed between the earth and the sun. This space vehicle can effectively weaken the astronomical solar radiation onto the earth, reducing the global warming. According to the force analysis of the system, the dynamic equation of the aircraft is obtained. Next, through the dynamics simulation the working of the huge space shield in elliptic orbit is considered by "link-spring" model. And the system would not failure in space by the static calculation. Therefore, this paper not only describes the feasibility of this new scheme, but also the analysis and simulation method could be applied to the establishment of the other similar tethers system.
