Force identification by using support vector machine and differential evolution optimization

Abstract

A novel method is presented to determine the external dynamic forces applied on structures from measured structural responses in this paper. The method utilizes a new SVM-DE model that hybridized the differential evolution (DE) technique and support vector machines (SVM) to resolve the problem of force identification. Both numerical simulations and experimental study are conducted to demonstrate the effectiveness, robustness and applicability of the proposed method. It is promising that the proposed method is practical to the real-life application. © 2010 Springer-Verlag Berlin Heidelberg.
