Abstract
The dynamics characterisation and modelling of a flexible cantilever (fixed-free) beam in transverse motion is presented in this paper. Finite Difference (FD) numerical analysis method is used to simulate the vibration of flexible cantilever beam system. The FD algorithm developed is validated through comparison of its natural frequencies of vibration with the theoretical values. Using input-output data obtained via FD simulation, nonparametric system identification of the flexible beam using intelligent Neural Network (NN) and Adaptive Neuro Fuzzy Inference System (ANFIS) are developed. Results indicated a comparable performance of both intelligent algorithms in modelling the flexible beam. The simulation environments produced in this research can later be utilised as a platform for development and verification of an active vibration control of the flexible cantilever beam.
