Abstract

A numerical model for the simulation of slider flying characteristics and frequency response in helium-air gas mixtures has been developed. The dynamic flying characteristics of the slider are obtained by simultaneously solving the Reynolds equation and the slider equilibrium equations. The contact force, friction force and adhesive force at the slider/disk interface are investigated using a slider/disk contact model. Frequency analysis shows that the second pitch mode of the slider is shifted to a higher frequency with an increase in the percentage of helium.
