In order to solve the problem that the evolution law of the damping performance of squeeze film damper (SFD) under the condition of single oil supply hole is not clear, the fluid domain simulation model of the squeeze film damper was established. Various clearance ratios, length-to-diameter ratios, oil groove cross-sections, and positions were considered in the model. The influences of structural and working conditions on the damping stability were analyzed. The influence mechanism on the damping performance was revealed. The results showed that increasing the eccentricity, clearance ratio or decreasing the aspect ratio can improve the damping stability. And increasing the whirl frequency, aspect ratio or decreasing the eccentricity can help to improve the damping value of the oil film. Under asymmetric oil supply conditions, a trapezoidal groove provided higher damping, while a square groove offered greater stability. A centrally located groove maximized damping, whereas an eccentric placement enhanced stability. This study could provide crucial theoretical support and optimization guidance for the design of squeeze film dampers under single-oil-hole supply conditions, offering significant value for engineering applications.
