포일 스러스트 베어링의 범프 포일 형상과 포일의 열처리에 따른 구조강성과 감쇠 비교

Abstract

The current study compares structural stiffness and damping coefficients of three different types of foil thrust bearings. Overall structural stiffness and damping coefficients largely rely on the under-spring configuration. Furthermore, additional heat treatment of the bump foil greatly enhances the structural characteristics of the test bearing.
