    Numerical simulation and topology optimization of slider air bearing by Li, Qiang

    Published 2008
    “…Since the first commercial hard disk drive was developed in 1956, the stability of the flying attitude is always an important factor to be considered in the slider air bearing design. The objective of this dissertation is to develop an efficient computational modeling technique for simulating the air bearing slider (ABS) in hard disk drives and ultimately develop an effective topology optimization methodology to systematically and automatically design the air bearing slider with a target of achieving a near-constant flying attitude when the slider moves over the surface of the hard disk drive. …”

    Bio-based lubricant with additives: Tribological performances in hydrodynamic journal bearing by Norazman, Amanda, Paiman, Zulhanafi, Samion, Syahrullail, Afiq, Muhammad Noor, Muhammad Yazid, Witri, Rasep, Zuraidah

    Published 2024
    “…Purpose: The purpose of this paper is to investigate the performance of bio-based lubricants (BBL), namely, palm mid-olein (PMO) enriched with an antioxidant agent, tertiary-butylhydroquinone (TBHQ) and a viscosity improver, ethylene-vinyl acetate (EVA), in journal bearing (JB) applications. Design/methodology/approach: Samples of the BBL were prepared by blending it with TBHQ and EVA at various blending ratios. …”

    Passive acoustic tracking of an unmanned underwater vehicle using bearing-Doppler-speed measurements by Kita, Kristen Railey, Randeni, Supun, DiBiaso, Dino, Schmidt, Henrik

    Published 2024
    “…The propeller rotation rate can be estimated from the motor signature and converted to speed using a pre-identified model of the robot. The bearing-Doppler-speed measurements outperformed traditional bearing-Doppler target motion analysis: the bearing, bearing rate, range, and range rate accuracy improved by a factor of 2×, 16×, 3×, and 6×, respectively. …”
