Abstract: The support vector machine(SVM) can be used for training and classification in the condition of small samples.This paper presented a detection method of AC contactor holding vibration based on SVM.Firstly,a small number of vibration time domain signals from the base plate of AC contactor which is not qualified for vibration test are extracted,then a virtual vibration test classifier is established by training the sample data and using support vector classifier(SVC).The experimental results show that the method has a good classification and recognition ability for the samples of the follow-up contactor.
