Characteristics of Three-Fixing-Lobe Journal Bearing during Start-up Process

Journal bearing with three fixing-lobes was taken as the research subject.The change regulars of motion track of journal center and the dynamic characteristics and stability of journal bearing with three fixing-lobes were studied during start-up process by solving the Reynolds equation with finite difference method.According to the fact that with the angular speed increasing the dimensionless load capacity decreases,a series of curves of the relation between the dimensionless load capacity and length-to-dia...
