Fretting degradation has long been recognized as a major failure mechanism for electrical connector systems. In certain circumstances, such as for vehicle applications, connectors are exposed to exterior environments and could easily be infiltrated by dust and other particulate contaminants through the housing or during the mating process. The presence of particulate contaminants during vibration...
Two of the major drivers for fretting corrosion are vibration and thermal cycling, with most previous studies focusing on experimental evaluation. It would be useful to develop and test a strategy for using computer modeling techniques to simulate the effects of vibration and thermal cycling induced fretting corrosion. Toward this end, finite element models are developed for a single blade/receptacle...
For automotive applications, the mechanical behaviour of the contact area under vibrations is one of the key factors for connector reliability. Such vibrations are typically in the range of 10-2000 Hz and result in displacements of only a few microns, at the contact interface. In the present study, a bench test has been developed to control more representative motions down to 1 μm. The objective is...
Relatively little is known about the fretting mechanism of high power connectors used in hybrid vehicles, even though the vehicles are widely being introduced to the market. This work experimentally investigates the fretting mechanisms of silver-plated high power connectors caused by vibrations. In order to emulate operational and environmental effects, a test stand was designed that is capable of...
