Effect Of Hdd Mounting Stiffness And Damping On Hdd Vibrations Induced Characteristics of structurally transmitted hard disk drive (hdd) vibrations induced by different built in vibration sources, including speakers, fans and a cd dvd drive in a notebook. Elastic mounts with cushioning materials are often used to minimize the likelihood of failure in such cases. in this paper, we analyze the dynamic characteristics and shock response of the vibration isolation systems supporting hdds.
Effect Of Chassis Stiffness And Damping On Hdd Vibrations Induced By In this paper, a theoretical model to analyze the vibration transmission from the speaker, cooling fan, and cd dvd driver to the hdd is presented. in the model, the vibration source, chassis and hdd are represented as lumped mass with spring and damper supported. Hard disk drives (hdds) in laptop personal computers (pcs) are subject to impact induced failure, as well as to operational vibrations. elastic mounts with cushioning materials are often used to minimize the likelihood of failure in such cases. Abstract: notebook pcs, especially its hard disk, suffer impact induced failure as well as vibration problems. consequently shock and vibration performance plays a decisive role in the product design. to minimize the likelihood of failure in such cases, cushioning materials are often used.

They used six different rubber mounts with different damping and stiffness characteristics to protect the hdd against shock and vibration. As hdds increase their data density and spin speed, hdd vibration becomes more and more important. excessive vibration of hdds can not only cause read write errors in operation, but also reduce yields in manufacturing processes (e.g., during servo writing). According to the operational characteristics of hdd suspension, the present work is focused on the topology design of hdd suspension for the dynamic shock response problem. The main objective of this work is to propose a new piezoelectric shunt damping methodology for the suppression of the coupled vibration between external structures (base plate and drive cover) and the hdd disk spindle system.
