| Abstract: | This study presents elastically supported Timoshenko column with attached masses for free vibration analysis using fuzzy
neural network. Neuro fuzzy frequency estimation (NFEE) models were developed to compute vibration frequencies using
fuzzy logic toolbox of software Matlab 7.0. Gaussian membership functions and adaptive neuro fuzzy inference system (ANFIS)
were used in NFFE model. Hybrid learning rule was applied for quantifying output variables in NFFE model. Frequency
values of column with 1, 5 and 10 attached masses were computed. Training sets for NFFE models used transfer matrix method
(TMM). During testing of NFFE model, good agreement was observed with results obtained using TMM as reduction in computation effort. |
