Description:
Considering the effect of tether sag of situation, submerged floating tunnel tether-tube parameter resonance mathematical model and the nonlinear equations of motion are built. Then the equation method is simplified by the Galerkin method, meanwhile, MATLAB is used to solve this equation. The parameter resonance which can occur between the constraints is analyzed. The results show that frequency ratio between submerged floating tunnel tether and tube is in an area. Parameter resonance phenomenon occurs among them. Under the condition of tether damping ratio unchanged, if the damping ratio of tube is increased, their resonant parameters of probability may be reduced to some extent.
