  • Active vibration isolation device based on electromagnetic and aerostatic floatation
    Patent number: 9145945
    Abstract: 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.
