Abstract

Vortex-induced resonance is a complex coupling phenomenon. Vortex-induced vertical force (VIVF) model describes the characteristics of the vortex-induced force in resonance. Improper parameters can distort the model, so accurately identifying the parameters of the model is a current research hotspot. In this paper, a parameter identification method based on model degradation is proposed. A constant term is used to replace the harmonic force term in the model. The degenerated model is a linear combination of the nonlinear basis functions. Therefore, the linear fitting method is used to identify the model parameters. Based on the fit of VIVF, the performance of identification algorithm is evaluated. The results of Wilcoxon’s and Friedman’s nonparametric tests show that the identification algorithm is the best.
