Abstract :
Taguchi method was applied for designing head suspension assembly for mobile hard disk drives (HDDs). Operational shock resistance and positioning accuracy are very important. Control factors of suspension shape were selected and shock resistance and frequency response analysis by finite element method (FEM) simulation were conducted for L18 orthogonal array. New suspension design has achieved good shock resistance and frequency response function. Measurement results had good correlation with FEM simulation
