Authors have studied the degradation phenomenon on contact resistance under the influences of an external micro-oscillation.
They have developed a hammering oscillating mechanism (HOM) or a micro-sliding mechanism 1 (MSM1) which provides micro-oscillations for electrical contacts.
It is shown that each mechanism is able to simulate an actual degradation phenomenon on electrical contacts.
And they have also developed the third mechanism, namely another micro-sliding mechanism 2 (MSM2) which provides micro-sliding driven by a piezo-electric actuator and elastic hinges, which has more precise sliding performance, less thermal drift on the sliding, and smaller sized system constituted of commercial parts.
In the previous paper, by the MSM2, they consider the theoretical analysis and experiments on input force waveform or output displacement response in the case of three types of input waveform as force which are a sinusoidal, a rectangular, and a pulsive ones.
In this paper, they obtain the experimental results concerning ``minimal sliding amplitude'' against force waveform when resistances on electrical contacts fluctuate under the conditions which are six types of waveform as the above and three levels of frictional force which are usual (1.6 N/pin), middle (1.0 N/pin), and smaller (0.3 N/pin) between a male-pin and a female-part using the MSM2.
And, they compare the differences on the above minimal sliding amplitudes under the conditions by dispersion analysis on statistical test.
Consequently it is shown that that the larger the frictional force is the larger the minimal sliding amplitude is and that the amplitude in a sinusoidal one is larger than in rectangular or pulsive ones.
However, it is not shown that the differences in the amplitudes in pulsive one are clear. |
