Abstract

In this study an advanced monitoring technology has been presented based on the electrostatic induction principle to monitor timely wear fault online The paper begins with the principle of the electrostatic monitoring technology then we focus on the electrostatic sensor the most important component in the electrostatic monitoring system establish a measurement model for an electrostatic sensor with the given structure parameters Based on the measurement model we use the finite element method to analyze the characteristics of an electrostatic sensor for wear debris detecting in lubricating oil Lastly we build an experiment platform to validate the feasibility of the electrostatic monitoring method The experiment results show to some extent that the electrostatic signal can reflect the relative density of wear debris and the sensor proposed can satisfy the primary demand of wear debris online monitoringThis work was supported by the Aeronautical Science Foundation of China 2012ZB55003 and partly supported by the National Natural Science Foundation of China 51105344 a grant from the Basic Research and Advanced Technology Program of Henan Province 132300410269 the Opening Project of Key Laboratory of Precision Manufacturing Technology and Engineering Henan Polytechnic University of China PMTE201001B The authors also wish to thank them for their financial support The authors would like to thank them for their financial support
