Research Progress of Stewart Vibration Isolation Platform

Many fields, such as optics, aerospace, ultra precision machining, etc., have high requirements for vibration in all directions of the system. Stewart platform is widely used multi degree freedom active isolation. This paper summarizes isolation platform. Firstly, it introduces structure platform, including various configurations, flexible kinematic pairs, actuators, and influence different structures on practical applications. Then modeling introduced, methods, advantages disadvantages are summarized from aspects kinematics dynamics. Thirdly, control technology application development main methods summarized. Finally, combined with recent ten years, this points out shortcomings existing research direction improvement.
