| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have developed the mechanism which gives vibration to electrical contacts by hammering and studied the influences of a micro-oscillating on contact resistance. Over 7.5 millions of hammering, the resistance almost was 200Ω. And over 17 millions of hammering, it fluctuated between 200Ω and 1000Ω. By 45 millions of hammering it was almost 1000Ω．On the other hand, we also developed the mechanism which gives micro-sliding to electrical contacts for comparison. This mechanism could detect the degradation phenomenon on these by influences of repeated sliding operations. Over 100 thousand of sliding, the resistance of the contacts started increasing, and after that the resistance fluctuated in between 20Ω and 400Ω. Although the two mechanisms are completely different( in methods, numbers, etc ), the results of two tests were almost similar on the oscillating phenomenon. | |
