Abstract

Designing and dynamics research of six degree of freedom maglev vibration isolation system were conducted. The structure of maglev vibration isolation platform was designed, and the stator of the vibration isolation platform, locating in the vibration source, was analyzed by finite element software. By analyzing the coupling characteristics of the system under the influence of different disturbing force, nonlinear dynamic model for control was established and nonlinear dynamics behavior of the system was simulated. Research of the nonlinear dynamic model will provide a basis for the design of the control algorithm.
