Fluid film thrust bearings are commonly used in industry, providing durable and reliable operation at high values of load carrying capacity, accompanied by low friction losses. A major advantage of hydrodynamic fluid film bearings, over other types of bearings, is their enhanced dynamic behaviour, especially under transient or impact loads. Currently, a systematic approach to identify the dynamic coefficients of thrust bearing geometrical configurations utilising high complexity CFD simulation data has not yet been established. It is therefore imperative to develop a method, capable of evaluating the dynamic characteristics of complex bearing designs and allow the evaluation of bearing response under transient loads. In the present work, a computational approach is proposed to estimate the stiffness and damping coefficients of fluid-film thrust bearings. A CFD-based ThermoHydroDynamic (THD) numerical model of the bearing is developed and utilised for performing an initial steady...

推力轴承动态系数的计算评估；变形对热流体力学性能的影响

液膜推力轴承在工业中通常使用，可在高承载能力值下提供持久而可靠的运行，并具有低摩擦损耗。与其他类型的轴承相比，流体动力液膜轴承的主要优点是其动态性能增强，尤其是在瞬态或冲击载荷下。当前，尚未建立使用高复杂度CFD模拟数据来识别推力轴承几何构型的动态系数的系统方法。因此，迫切需要开发一种方法，该方法能够评估复杂轴承设计的动态特性，并能够评估瞬态载荷下的轴承响应。在目前的工作中，提出了一种计算方法来估计液膜推力轴承的刚度和阻尼系数。开发了基于CFD的轴承ThermoHydroDynamic（THD）数值模型，并将其用于执行初始稳态...
