The evaluation method of sensor location for transmission fault diagnosis

Abstract

In the experiments of the transmission fault diagnosis, acquiring vibration signals from three measurement locations by multi-sensors. Using improved fastICA algorithm to de-nosing and order analysis algorithm to get the order spectrum, the paper proposed two evaluation indexes. According to the experiment result by using evaluation indexes, the fault characteristics contained in the vibration signals from three measurement locations are different. Then, the best location can be chosen as measurement location to improve the accuracy of fault diagnosis.
