*School of Mechanical Engineering, Yeungnam University*Graduate school of Mechanical Engineering, Yeungnam University(Received May 4, 2011; Revised August 10, 2011; Accepted August 20, 2011)Abstract − In this study, the characteristics of herringbone grooved air thrust berings are studied. It is shown thata generalized coordinate transformation method which was developed for handling complex geometry such asherring bone groove journal bearings is well applied to herringbone grooved air thrust bearings. The load car-rying capacity and stiffness and damping coefficients are calculated according to the design parameters likegroove depth or the number of grooves and compared to that of plain air journal bearings.Keywords − herringbone groove(헤링본 그루브), air thrust bearing(공기 스러스트 베어링), analyses(해석), generalized coordinates(일반좌표계)
