Although this mechanism is simple, but some components will break down after serve for a while. Therefore, the aim of this research is to using order analysis for fault diagnosis in CVT. The pattern of each fault of CVT can be found from measured noise signal in the speed-up process by using re-sampling algorithm. In order to find the characteristics of each fault, the first part of this research is to test CVT on an experiment platform which is driven by an electric motor and the rotating speed of motor is controlled by a variable speed drive. Then the CVT is tested on a motorcycle to verify the robustness of this method. All the experiments are proceeded in a semi-anechoic chamber. The results show that order analysis can be useful for fault diagnosis in CVT.
