Effect of Vibration Frequency on Mechanical Behavior of Automotive Sensor

International audience; Due to repetitive micro-displacements, the fretting phenomenon was defined as an electrical and mechanical degradation of the electrical contact interface in automotive sensors. Commonly, the electrical degradation was quantified by the increase of contact resistance deduced from the contact voltage. This work aims to address the analysis of relative displacements according to three space directions between sensor components in contact for different vibration frequencies for a Top Dead Center sensor. Particular attention was paid to measurements of displacements near crimping zones. © 2019, Springer International Publishing AG, part of Springer Nature.
