Abstract

 This paper presents a theoretical study on the transient characteristics of fuel cell air compressor supported by water lubricated journal bearings. The nonlinear trajectory of the compressor rotor bearing system under a half sinusoidal shock load is numerically calculated by simultaneously solving the rotor motion equations and the Reynolds equation. In order to take the possible contact between the shaft and sleeve into consideration, the pressure-compliance relationship of roughness contact is also introduced. The results show that the anti-shock performance of the compressor satisfies the requirement of vehicle application.
