Concerning contact resistance prediction based on time sequence and distribution character

We take statistics on experimental data, including static contact resistance, bounce time and the max contact resistance of relay´s matching contacts in the dynamic closing process. A conclusion is drawn that the contact resistance is not in obedience to the normal distribution function. The further analysis makes clear that the contact reliability on contacts has correlation with the eigenvalues of diagnostic parameters and the figure of their distribution density curves. The reason for these is discussed preliminarily. On the ground of the above work, we develop the contact resistance prediction model based on time sequence and distribution character.
