The aircraft hydraulic system has a significant impact on the safety of modern civil aviation. The wear of the hydraulic pump is the main cause for the performance degradation of the aircraft hydraulic system. In this paper, changing of oil return flow in hydraulic system under the wear condition of slipper and cylinder bore is studied. Firstly, the factor and mechanism of the degradation of the hydraulic...
Journal bearing is a kind of widely used bearing and its study never stops. The analysis is carried to journal bearing with layered viscosity model in this paper. Layered Viscosity Model regards viscosity as piecewise function and averages every segment in order to get more accurate expression, and the pressure distributing, load capacity and friction are obtained for journal sliding bearing under...
