| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Authors have studied the influence on electrical contacts by actual micro-oscillation using some oscillating mechanisms (Hammering Oscillating Mechanism, Micro-Sliding Mechanism, Tapping Device etc.). In this paper, first, the authors compare cyclic metal ball drop test with hammering oscillating mechanism on the performance of acceleration and force for the hammered object, and show that the distribution of the data by the latter is much smaller than the former. Second, they propose a simple and practical protocol to estimate an effective mass, effective force and effective acceleration of the electrical devices on the PCB (printed circuit board) using hammering oscillating mechanism. Third, they discuss the degradation mechanism on electrical contacts under the influence of micro-oscillation from the effective force and the frictional force, and indicate the correlation between the former and the latter. Finally, they estimate the damping ratio and natural frequency of the system on the assumption that there is transient response characteristic with impulsive concentric load in the effective acceleration. | |
