Researches on Nonlinear Hybrid Vibration Isolation System

Abstract:

In this paper, the dynamics of nonlinear hybrid vibration isolation system is carried out for a qualitative analysis, based on the algorithm of synovial variable structure the control model of hybrid vibration isolation system is designed, and then the validity of the control model is verified by relevant examples in the condition of nonlinear stiffness. Moreover, the simulation results show that: the control performance of nonlinear hybrid vibration isolation is better than passive vibration isolation and linear vibration isolation system, and the introduction of nonlinear stiffness can effectively reduce the force transmited to foundation. The control methods studied in this paper has an important guiding significance to design the nonlinear hybrid vibration isolation system in the practical engineering.
