Design and analysis of cushioning packing box for Chinese Small Telescope Array

Dome C and A of the Antarctic plateau is considered to be the best astronomical site on the earth because of extremely cold, dry weather, low wind speed and atmospheric turbulence overhead. CSTAR (Chinese Small Telescope ARray), which is composed of four small telescopes with 100mm clear aperture, has been accomplished in August and shipped to Antarctic at November 2007. Then, from the Zhongshan station, Chinese traverse team sledged it by snow tractor to Dome A through about 20 days hard trip and erected in January 2008. In this paper, the vibration proof design of packing box of CSTAR is introduced based on vibration theory and the analysis of power spectrum density is done to verify parameter selection. Finally, transport experiment is done to prove that packing box is suitable for the inclement and various transport condition.
