【Abstract】 Based on the coincidence of mass and stiffness, the system decoupling study was carried out, and the results showed that the decoupling system could significantly reduce the adverse effects of non-decoupling system. Based on the decoupling from the load, the dynamic analysis of the double chamber air spring was carried out, and simultaneously the hybrid control consisted of air spring system and active control was performed out. In industrial engineering vibration control, linear isolators were mostly utilized for power equipment, and it was necessary to realize system decoupling as much as possible. The vibration control of precision equipment was mostly based on air spring flotation, in which decoupling from the load should be realized as much as possible on the basis of system decoupling. Finally, the hybrid control should be resorted to when passive control could not satisfy the harsh requirements.更多还原
