AbstractWe investigate the nonlinear random vibration of the cables with small sag and excited by colored noise being filtered Gaussian white noise uniformly distributed on the cable. The nonlinear multi-degree-of-freedom systems are formulated based on the revised equation of motion of the geometrically nonlinear cable with Galerkin method. The nonlinear MDOF systems governing the motion of the cable at a given point are formulated and analyzed when the excitation is the filtered Gaussian white noise governed by linear second-order stochastic differential equation. Numerical results obtained with the state-space-split-EPC method, Monte Carlo simulation, and equivalent linearization method are given and compared. The computational efficiency and numerical accuracy of the three methods are also compared.
