摘要：
Based on Euler-Bernoulli beam theory and time-delay feedback control strategy, the wonlinear vibration control equation of a tension leg in submerged floating tunnel under parametric excitation was established. Using Galerkin method and linear stability analysis, stability boundary conditions of the control system under time-delay action were obtained. Effects of different control parameters on the tension leg's vibration response were analyzed through numerical calculation. The results showed that the reasonable time-delay value and gain value can greatly reduce vibration responses of the tension leg in underwater suspension tunnel, and improve its structural stability. © 2021, Editorial Office of Journal of Vibration and Shock.
