Keywords: Farm tractor, frequency response test, nonlinear dynamics, and wavelet analysis
This paper discusses the application of wavelet in the analysis of time series data obtained from the experiments on the nonlinear dynamics of farm tractors. The experimental investigation was carried out by frequency response test. This was done by running the tractor on two types of artificial test tracks made of angle irons over a wide range of travel speeds. In the analysis, the wavelet used was Coiflets (Coif4) which is among one of the popular wavelets being used in the area of digital signal processing. By using simple linear models as well as nonlinear/chaotic models, the analysis of the experimental chaotic time series data is possible.(Download PDF) (Export to EndNotes)
