Design considerations for reducing shock responses of a micro-drive

Abstract

Based on the operational shock simulation of the head disk assembly (HDA) of a micro-drive, we proposed three possible approaches for reducing the shock responses. These approaches are, 1) to change the Young's modulus, 2) to change the thickness of the hinge, and 3) to change the boundary condition of the disk. Numerical results show that the third approach with a clamped boundary condition for the disk produces the most significant effect on reducing the shock responses.
