摘　　要：针对作者提出的锯齿形多槽式动静压气体润滑轴承，其支承刚性对称轴系进行稳定性分析，并给出计算实例．The stability is of importance to high speed gas-lubricated bearings. Unfortunately,lit-tle has been reported on investigations on the stability of gas-lubricated bearings with sur-face-restriction compensation by grooves. Based on 8 dynamic coeHicients of a new hybridgas-lubricated journal bearing with surface-restriction compensation by multiple sawtoothgrooves proposed by the authors,the stability of the rigid rotor-bearing system is studied.The stability criterion and the calculation of the critical state are discussed.The eHect of de-sign parameters of the bearing on the stability is investigated and an example is given.
