弹性薄片气体动压轴承(简称薄片轴承),因其高速动态性能优良而越来越广泛地应用于航空航天、民用高速机械(如气体涡轮增压器、高速离心机、制氧机、气流纺纱机、液体火箭推进系统、轨道运输器)等领域。在某些苛刻的使用环境下,非薄片轴承莫属,如在高温气体透平支承中,轴承的环境温度已达760℃情况下,一般 Flexible sheet gas dynamic pressure bearings (referred to as sheet bearings), because of its high-speed dynamic performance and more and more widely used in aerospace, civilian high-speed machinery (such as gas turbochargers, high-speed centrifuges, oxygen machines, air spinning Yarn machine, liquid rocket propulsion system, rail transporter) and other fields. In some harsh environments, none other than non-sheet bearings, such as bearings in high temperature gas turbine bearings, the ambient temperature has reached 760 ℃, the general
