Authors developed the mechanism which gives real vibration to electrical contacts by hammering oscillation in the vertical direction similar to real cases and studied the influences of micro-oscillating on contacts. It is shown that the performance to measure acceleration and force by Hammering Oscillating Mechanism (HOM) is more outstanding concerning both of the stability and the distribution of data than the other method. Much simpler and more practical protocols are proposed to estimate not only acceleration but also force or mass by measuring acceleration. And it is indicated that the mechanism on impulsive load and frictional force is concerned with one of the causes of the degradation phenomenon of electrical contacts. |
