摘要：
We created a finite-element model of the head-disk assembly (HDA) of a small-form factor drive. We conducted operational shock simulation and modal analysis with this finite-element model, and investigated the pulsewidth effect of a half-sine acceleration pulse on the shock responses. We found that the umbrella mode of the disk is the dominant mode for operational shock. Numerical results of the pulsewidth effect on the maximum shock responses further confirm the conclusions in a previous work by the authors.
