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. Using an evaluating method (Method 1), the real dynamical parameters: to effective mass, effective force, and effective acceleration are obtained under the influence of external micro-oscillation. In addition another evaluating method (Method 2) reaches the real dynamical parameters: natural frequency and damping ratio. It is possible to known the values of effective mass m, effective force F and effective acceleration α0 from Method 1 in previous paper and natural frequency ω0 and damping ratio ζ from Method 2 in this paper. And it is possible to obtain the approximate dynamical properties of the objects by some equations. |
