Global Behavior Analysis of the Quasi-zero Stiffness Vibration Isolation System with Flexible Foundation
摘要
Abstract
With the quasi-zero stiffness isolation system on a flexible foundation as an object, the dynamic model of the nonlinear vibration isolation system is established and its bifurcation characteristics are analyzed in a large range of parameters. The attractor and its attracting basins are investigated by using the point mapping method and selecting several analytical planes. The coexistence of periodic attractors is analyzed. The results show that the quasi-zero stiffness nonlinear vibration isolation system exhibits a very complicated dynamic behavior with the change of amplitude of the excitation force, and the coexisting of attractors. The occurrence of motion of period 3 makes the system to have some sensitivity to the initial conditions.关键词
