Asymptotic Methods for an Infinite Slider Bearing with a Discontinuity in Film Slope.

摘要

The method of matched asymptotic expansions is used to develop an asymptotic expression for the pressure for large bearing numbers for the case of an infinite slider bearing with a general film thickness that has a discontinuous slope at a point. It is shown that, in addition to the boundary layer of the pressure at the trailing edge, there is also a boundary layer in the derivative of the pressure at the point of dicontinuity. The corresponding load formula is also derived. The special cases of the taper-flat and taper-taper slider bearings are discussed. (Author)
