The wide application of switched reluctance motor has been limited due to its high acoustic noise, which is mainly caused by radial vibration. In this study, a new radial vibration model is proposed consisting of vibration acceleration impulse model and natural oscillation model. The vibration acceleration impulse model is developed based on the measured sample data using least-square support vector machine method. Natural oscillation model is also proposed based on the superposition of each frequency, which is obtained by finite element method. The vibration model is built up in MATLAB/Simulink and various experiments have been conducted to verify the accuracy of the proposed model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
