| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The authors have developed the hammering oscillating mechanism which could give real vibration to electrical contacts and made experiments with total operation’s number, about 42 millions. After the term was passed, the contact resistance increased to about 200Ω. The tendency continued till the end. By using the connectors with smaller contact’s force they made experiments with total operation’s number, about 44millions. After the term was passed, the contact resistance increased to about 600-1000Ω. On the contrary, by using the sliding contact mechanism they made experiments with total operation’s number, about 24 millions. After the term was passed, the contact resistance increased to about 200Ω. And inputs of hammering oscillating mechanism’s data were applied to 3-D oscillating mechanism, which generated quasi-damping oscillation and they made experiments with total operation’s number, about 6 millions. Although the three mechanisms are completely different (in principles, methods, numbers, and so on ), the results of three measurements were similar on the oscillating phenomenon. It was suggested that the three mechanisms could detect the more real degradation phenomenon on contacts with the influences of micro-vibration by applying the model of fretting corrosion to the fluctuation of contact resistance. | |
