다엽형상의 포일을 사용한 공기 저널 베어링의 정특성에 관한 연구
A study on hydrostatic characteristics of air-lubricated journal bearing using multi-leaf type foils
초록
The characteristics of multi-leaf feil bearing are investigated. The Foil bearing is preloaded and has several leaf foils modeled by curved beams. An analysis of the air foil bearing was performed, considering effects of foil deflection and compressible lubrication equation simultaneously. A parametric study shows that the number of foils significantly affect the static characteristics of air foil bearings and describes what the minimum film thickness means. The results include pressure profile, load capacity, dimensionless torque and minimum film thickness in the foil bearing.
