The current work scrutinizes the impact of turbulence on the dynamic performance of the novel variation of hydrodynamic bearing, especially “Non-Circular Floating Ring Bearing”. A bearing comprises of a shaft, floating ring, and non-circular outer housing. The journal and floating ring are cylindrical, whilst the outer housing is noncircular. The noncircular designs of journal bearing provide better stiffness characteristics. The well-established Navier–Stokes and continuity equations (cylindrical coordinates) have been adequately utilized with the linear turbulence lubrication theory. Dynamic characteristics of modified floating ring bearing have been scrutinized at different numerical values of film eccentricity ratio (outer) and Reynolds numbers up to 9000. The current analytical work envisages satisfactorily well performance of modified floating ring bearing in the regime of turbulence.

湍流对非圆浮环轴承动态性能的影响

目前的工作仔细研究了湍流对流体动力轴承的新型变体，特别是“非圆形浮环轴承”的动态性能的影响。轴承由轴、浮动环和非圆形外壳组成。轴颈和浮动环是圆柱形的，而外壳是非圆形的。轴颈轴承的非圆形设计提供了更好的刚度特性。完善的 Navier-Stokes 和连续性方程（圆柱坐标）已充分利用线性湍流润滑理论。在薄膜偏心比（外）和雷诺数高达 9000 的不同数值下，改进了浮动环轴承的动态特性。
