#18275–Electrical Chatter Analysis of Components under Multi-Axis and Single-Axis Vibration Testing

Vibration testing is an important step in the development of modern electrical components, ensuring the reliability and performance during pertinent operating environments. Components are often required to transfer information in the form of electrical signals during vibration environments which often cause increased contact resistance (electrical chatter) and degradation of the signal output. The characterization of component electrical chatter is traditionally performed with single degree of freedom (SDOF) vibration stimulis. Of interest, is how the introduction of multi-degree of freedom testing (MDOF) alters the electrical chatter performance of the component. In this study, MDOF excitation tests are conducted using a Team Tensor TE6-900 six degree of freedom shaker at increasing levels of excitation while an in-situ NI-my Rio evaluation board is used to measure and record electrical chatter events. To narrow testing scope, a space vector machine learning algorithm tool is used to down select the necessary testing data set. Interesting mileposts during the process, experimental response and analysis are discussed.
