| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Authors developed the mechanism which gave real vibration to electrical contacts by hammering oscillation in the vertical direction, and studied the influences of a micro-oscillating on contact resistance. First, they defined the mathematical model toward hammering oscillating mechanism and carried out theoretical approach by using solution methods for inverse problems. By delta function and step function as an external force, they have simply made modeling and simulation for the mechanism. It was suggested that the mechanism could make an acceleration test of actual degradation phenomenon on contacts by the influences of a micro-oscillation. Second, they measured the fluctuations of the electrical contacts in the three conditions (150G & 2.0N, 150G & 0.3N and 400G & 2.0N). It was shown that the fluctuations were occurred in all cases but the time-series pattern of the fluctuation was different from each other in the points of contact resistance, starting number and so forth. It should be considered more carefully that how is the phenomenon occurred to pay much more attentions to other factors like those of electrical, mechanical, physical and chemical factors. |
