Flow Induced Vibration Analysis In Pipeline By Using Oneway And Two Way Flow induced vibration reduction in hdd by using a spoiler hirono, y. ; arisaka, t. ; nishijima, n. ; shimizu, t. ; nakamura, s. ; masuda, h. We report on large eddy simulations of the turbulent flow of air in hard disk drives (hdds) using a commercial cfd code. in particular, we focus on hdd casings in which flow induced vibrations are reportedly reduced by small geometrical modifications. In this paper, the effects of two flow induced vibration (fiv) mitigation components on hard disk drive (hdd) airflow, vortex splitters and flow diverters, were verified. the edges of. To reduce the flow induced vibration (fiv) of the head stack assembly (hsa) in the hard disk drive (hdd), we experimentally studied the spoiler, which is put between disks. this study was carried out using a laser doppler vibrometer (ldv) to measure the amplitude of the head slider vibration.

The airflow patterns and characteristics of the flow induced vibration in hdd for three critical positions of the head gimbal assembly (hga) parked at the disks identified as id, md and od are investigated. Ional flow inside hdds can be reduced by using a spoiler, damper, disk separator and air shroud for decreasing the flow velocity inside. furthermore, filling helium gas inside hdds can reduce the vibration on the hga. because helium density is lower than air; its properties can improve the hdds. Achieving ultra high magnetic recording density in hard disk drives (hdds) requires clarification of flow induced vibration issues. in particular, it is necessary to reduce the flow induced disk vibration called disk flutter. P shaping for wideband disturbances attenuation 2.0 11 comparative study on the complex behaviour of flow fields in a transparent non axisymmetric tating system between two arm insertion angles at two measurement pla 0.4 0.
