... piezoelectric transducers transient response 03 02 2010 25 04 2011 21 07 2011 21 07 2011 For ultrahigh density magnetic hard disk recording, disks with super smooth surface are critical component for feasible air-bearing interface in nanometer range. To match up with the stringent...

.... The transient response of the line contact between two infinitely long cylindrical surfaces was simulated under a heavy step load function. The coefficients of friction were also presented in this work at steady condition with varying particle concentration. This simulation showed a significant effect of solid...

... the regression analysis of transient responses of an SPM (scanning probe microscopy) cantilever arising while separating from the target surface. The accuracy of measuring the cantilever displacement was greatly improved by mounting a silicon plate onto the cantilever as an optically reflective surface...

...Q. Zhu, Visiting Research Fellow,; W. J. Zhang, Associate Professor, This paper describes a nonlinear model and analysis of the axial transient response of the sector-shaped hydrodynamic thrust bearing-rotor system in a turbo-expander under a suddenly applied step load. The model is comprised...

...Eric M. Jayson; J. Murphy; P. W. Smith; Frank E. Talke A finite element model of a hard disk drive (HDD) is developed to investigate the transient response of an operational HDD subject to shock and vibration. The air bearing stiffness of the head disk interface is determined from a finite element...
