Abstract

Abstract

On the basis of displacement-time series, a nonlinear dynamics model is set up with support vector machine. The longest forecasting time is provided according to Lyapunov exponents and a standard cusp catastrophe model can be obtained through varibte substitution and function fitting. The results shows that this model can make satisfactory prediction results.
