The Harbin Institute of Technology is a research university and a member of the C9 League in China consisting of three campuses, which nearly span the country from north to south: the Harbin campus in Heilongjiang Province, the Weihai campus in Shandong Province and the Shenzhen graduate school in Guangdong Province.HIT undertakes research and numerous projects covered by official secrets which may have a bearing on its international ranking, although it is widely recognized as one of the top universities in the country, especially when it comes to local science and engineering league tables. HIT is one of only ten universities in the world that have designed, built, and launched their own satellites . It made the largest contribution to the success of the Shenzhou series spacecraft and Kuaizhou series spacecraft. One minor planet is named after the Harbin Institute of Technology and nicknamed "Hagongda Star" by the International Astronomical Union for HIT's achievements in science and engineering. Wikipedia.

This invention relates to an active vibration isolation installation based on electromagnetic and aerostatic floatation which is essential for the super-precision measurement and manufacture. It mainly consists of an isolation platform, an intermediate sleeve and a base. The isolation platform supports any object(s) placed on the platform and is supported by the intermediate sleeve. And the intermediate sleeve is supported on the base which is fixed on the ground. This invention uses the combination electromagnetic and aerostatic floatation to achieve large bearing capacity while excellent vibration isolation performance is maintained. This invention realizes automatic control of stiffness, using closed-loop speed control methods. It is therefore conclude that this invention can impose an excellent inhibitory action on the vibration originating from surroundings and the platform itself.
