Abstract ▼ AI-Helper

The paper presents extensive survey and review of experimental and analytical researches on fluid film bearings and squeeze film dampers (SFDs) for turbomachinery available in open literature (major archival international journals) published recently (2018 and 2019 only). Over 60 published research works are reviewed based on the research topics and objectives, the types of bearings, size of bearings, and main design parameters with a brief summary of experiments and/or predictions in each work. Some important findings and general observations about the experimental and/or predictive data are also presented. There are several major trends observed throughout the survey. A large portion of the papers focuses on bearing surface textures and effect of operating and assembly conditions on static and/or dynamic forced performances, as well as bearing surface roughness and wear patterns. Researches on geometry of orifices and recesses in hydrostatic (or hybrid) bearings, as well as bearing system stability predictions using thermohydrodynamic analysis and computational fluid dynamics (CFD), are considered as significant topics. Studies on SFDs mainly focus on experimental identification of force coefficients for various SFD geometries and sealing conditions. Reliable experiments of fluid film bearings and SFDs along with the development of experimentally benchmarked predictive tools enable reinforcement of the path for reliable implementations of the bearing components into high performance rotating machinery operating at extreme and harsh conditions. The extensive list of sources of recent experiments in the available open literature is a welcome addition to the analytical community to gauge the accuracy of predictive tools.

핵심어	질문	논문에서 추출한 답변
	유체 윤활 베어링이란 무엇인가?	유체 윤활 베어링은 오일, 물, 가스 등의 유체를 작동 유체로 사용하며, 베어링과 회전축 사이에 형성되는 얇은 유체막을 통해 윤활하는 베어링이다. 유체 윤활 베어링은 회전축이 회전함에 따라 회전축과 베어링 사이에서 발생하는 동적 압력으로 축하중을 지지하는 동압 베어링과 외부에서 가압 유체를 공급하여 축하중을 지지 하는 정압 베어링으로 분류된다.
	오일 공급이 없는 상태에서 SFD 성능을 확인하는 실험을 진행한 결과 알게된 것은?	[59]은 오일 공급이 없는 상태에서 구름 요소 베어링을 지지 하는 SFD 성능을 확인하는 실험을 진행하였다. 실험 결과 심각한 진동 문제가 발생하였으며, 회전축에 높은 불균형 질량을 가할 경우, 시스템이 비선형 거동을 나타내는 것을 확인하였다. 이에 따라 SFD 적용시 적절한 오일 공급은 시스템 안정성에 매우 중요한 요소임을 밝혔다. San Andrés et al.
	유체 윤활 시스템은 어떤 분야에 적용되고 있나?	이에 따라 터보기계의 고효율화를 위해 터보기계에 적용되는 기계요소에 대한 다양한 연구가 더욱 활발하게 이루어지고 있다. 유체 윤활 시스템은 자동차, 선박, 건설장비, 우주발사체, 그리고 로봇에 이르기까지 다양한 분야에 적용되고 있으며, 점차 그 중요성이 증가하고 있다. 이에 따라 최근 유체 윤활 베어링과 스퀴즈 필름 댐퍼(SFD)에 관한 다양한 연구가 활발히 진행되고 있다.
