ResumoIn 1979, Wedeven and Cusano [1] observed very interesting feature concerning EHL film which was influenced by a moving dent. That is, if the dent is on the faster moving surface, the film shape upstream of the dent is influenced by the dent. Ai and Cheng [2] solved numerically this problem using the multigrid method, and pointed out that the dent is extended in the direction of sliding with a rate approximately equal to the sliding velocity, resulting in the pressure increase at the edge of the dent in the direction of sliding. The present study offers more detail experimental results, by duochromatic optical interferometry, concerning the effects of a moving dent on EHL films.
