Abstract

The estimate of contact force and pressure at slider-disk interface is critical to the study of disk wear. Wear mechanism shows that the volume of wear is always proportional to the contact force or pressure. However, no exact experimental method can be used to measure the total contact force and real contact area. A computer simulation method is developed in this thesis based on the dynamic model, which takes account of asperity deformation and the statistical nature of asperity interaction. Elastic contact theory is adopted in the program. Using this simulation program, parameters which affect contact force and pressure are discussed; hence, a suggestion of using a "micro-slider" and small initial vertical velocity in start/stop operation is proposed in slider design.
