Dome A is the most remote region from the coast of the Antarctic, but it has a very important scientific value. The vibration and shock acceleration from Shanghai to Dome A is much larger than the ordinary road. The paper proceeds as follow: Firstly, the vibration acceleration from Shanghai to Dome A is introduced, and the largest location range is determined as the focus of the package cushioning design system. Secondly, a double layer floating raft vibration attenuation system is designed, and the parameters of the system is designed according to the vibration environment. Also the statics and dynamics analysis of the system is showed. In the winter of 2013, the actual test of this system has been done in MoHe China. The test results show that the system can meet the transport safety requirements of the telescope mirror.
