Authors have studied the influence on contact resistance by actual micro-oscillation to electrical contacts using some oscillating mechanisms. In this paper, the authors discuss an impact acceleration and load transferred to an object, which are important and fundamental elements of the hammering oscillating mechanism. They compare the performance of an improved cyclic ball dropping test, that of an improved cyclic cylinder dropping test and that of hammering oscillating mechanism (HOM). As a result of the comparison they obtain that there were less distributions of the measurement values by HOM than those of values by the improved cyclic ball or cylinder dropping test. Moreover by the HOM they measured the acceleration distributions in the various points of printed circuit board. Because they estimated the converted masses of the objects by using an acceleration pick-up and a weight, they obtained that the masses were different from each other. They illustrated correlative relationship between contact frictional force and the location on the printed circuit board by estimating impact load using the converted masses and accelerations. And by estimating accelerations without the pick-up they discussed the influence on the accelerations by the mass of the pick-up. |
