Abstract

In this study, the characteristics of the noise generated across the rotary slide contacts are clarified by proposing the rectangular window function (that is, the surface roughness model of contact) derived from the observation results of the noise waveforms and the shapes of contact´s surface changing for a long time. And, it is shown that the effective contact area can be simulated by the proposed rectangular window function and the proposed model is effective for the estimation of the noise generated across the rotary slide contact.
