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. By using the mechanism, “Micro-Sliding Mechanism II”, which is developed on trial, they obtain time-sequential fluctuation data of contact voltage. It is shown that there are quasi-stable and periodic closed orbits and bifurcation-like phenomenon in the data by using phase plane analysis. It is indicated that the data are able to be simulated by higher and lower frequency simple rectangular wave. It is also shown that there are stable and periodic closed orbits and bifurcation-like phenomena similar to the above and that there are different phenomena from the above. It is suggested that there is necessary to consider the non-linearity in the system for analyzing the difference caused the fluctuation of amplitudes or frequencies and data jumping.
