水中悬浮隧道涡激振动动力响应弹性梁伽辽金法Submerged Floating Tunnel Vortex-Induced Vibration Dynamic Response Elastic Beam Galerkin Method



In order to analyze the dynamic response of submerged floating tunnel (SFT) in uniform flows under vortex-induced vibration (VIV), equations of motion control of SFT were derived by simplifying SFT as a beam with elastic bearings. The analytical solution was presented by using the Galerkin method and the modal superposition method. The displacement curves of SFT at the intermediate span were gained by using Matlab. The nonlinear vibration characteristics about SFT were analyzed. The results show that both damping and spring of the elastic bearings have a role in reducing the response displacement of SFT, while the effect of stiffness of spring on the SFT is greater than that of damping coefficient.
