| Popis: | International audience; In automotive field, vehicle vibrations induce movement on hundreds of connectors which are located near the engine or inside the vehicle compartment. These vibrations produce induced-frictions between the male and female parts inside the connector (named pin and clip respectively) and generate electrical failure due to the well-known fretting-corrosion phenomenon. A relative displacement of 5 micrometers between the pin and the clip is sufficient to generate remains at the contact zone and set intermittent conduction at this interface which represents 60 % of electrical failure within a car. For our study, an automotive connector was submitted to vibration tests. The used bench is composed of a piezo-electric actuator which provides a controlled movement between the clip and the pin. A generator provides a stable current through the connector and all the measurement were performed with a voltmeter, a temperature controller and a scope for real-time analysis. The bench is mounted on an anti-vibration table in order to avoid external vibrations. The measurement of electrical behavior was undertaken under two kinds of atmosphere air and nitrogen gas. The use of air atmosphere shows a typical augmentation of the amplitude of the contact voltage whereas the use of nitrogen gas induces a contact voltage decrease. The measurement of this time characteristics provides new information to understand the fretting-corrosion phenomena © Proceedings of the 26th International Congress on Sound and Vibration, ICSV 2019.
