Modal contribution analysis of an operating complete flexible HDD affecting the head-disk motion due to shock

Abstract: This paper proposes a finite element modal and shock analysis of an operating complete flexible hard disk drive (HDD). It develops a finite element model of a complete flexible HDD including the spinning disk-spindle system with fluid dynamic bearings, the head-suspensionactuator with pivot bearings and air bearings, the base plate and cover with complicated geometry. The finite element model also includes a mounting table, which is a tetrahedron element with big mass, to simulate the shock to the HDD from the… Show more
