Perturbed Finite Element Analysis of Fold Bifurcations in Load/unload Bard Disk Drive Systems

Load/Unload 하드디스크 드라이브 시스템에의 Fold Bifurcations의 교란 유한요소 해석

The load/unload behavior of the hard disk drive slider is studied in terms of the air bearing static characteristics. The numerical continuation methods are applied to calculate suspension force - equilibrium position curve. The critical preloads of the femto size slider are analyzed. The hi-stability conditions are depicted on the skew angle - preload diagram. The perturbation method is used to check the stability of the solution branches.
