title = "Modal parameter estimation of the coupled moving-mass and beam time-varying system",
abstract = "The coupled moving-mass and beam system exhibits time-dependent characteristics, requiring time-varying dynamic models and corresponding modal analysis methods. The dynamic model of the coupled moving-mass and beam time-varying system under arbitrary excitation was firstly built; the influence of the moving-mass velocity and acceleration on the modal parameters was analyzed; and the modal parameters of the coupled time-varying system were estimated based on the non-stationary responses obtained through the state space representation in numerical simulation. An experimental system consisting of a simply supported beam and a moving mass sliding on it was set up. The responses of the experimental system under random excitation were measured and the modal parameters of the experimental system were estimated afterwards. The estimated results from the numerical simulation and the experimental system validate the time-varying dynamic model and indicate the effectiveness of the modal parameter estimation.",
