NUMERICAL ANALYSIS OF CONTACT MECHANICS BETWEEN SPHERICAL SLIDER AND DISK DUE TO INTERMOLECULAR FORCES

摘要

A numerical method for analyzing the elastic contact mechanics due to intermolecular forces between a spherical slider and a disk is presented and typical results for a 1-μm radius sphere (which simulates a roughness asperity), 2-mm radius sphere (test slider), and 10-30-mm radius spheres (magnetic head sliders) are given. A numerical method for evaluating intermolecular forces at contacting asperities is also presented.
