Summary:
Authors have developed some mechanisms which give real vibration to electrical contacts and studied the influences of a micro-oscillating on the contact resistance. Because it was necessary to deal with time-sequential data for analyzing the degradation phenomena of electrical contacts by the oscillating mechanisms, they tried to use non-linear data processing in addition to usually linear one. As a result of the trial it was shown that there were non-linear characteristic tendencies like a logistic model in a global area and limit cycles & bifurcation phenomenon in a local area in the fluctuation of the contact resistance of experimental results.
