以最小总功率损失为设计准则，提出了多凹腔静压径向轴承的设计问题。该设计受到凹槽面积与总承载面积的恒定比率以及给定凹槽几何形状的最大承载能力的约束。L/D比，偏心率，凹部面积与总轴承面积的比率，以及轴转速被认为是参数。该分析基于Raimondi和Boyd [1]的轴承模型。该模型通常适用于低速至中速，且凹槽面积与总轴承面积之比约为0.5或更大。设计图表的轴承具有的凹部面积的比例，总轴承面积为0.6，并采用毛细管和孔节流器，这些是最常见的类型的补偿元件。最后给出了一个设计实例来说明设计图的使用。
The design problem is formulated for multi-recess hydrostatic journal bearings with a design criterion of minimum total power loss. The design is subject to the constraints of constant ratio of the recess area to the total bearing area and maximum load capacity for a given recess geometry. The L/D ratio, eccentricity ratio, ratio of recess area to total bearing area, and shaft rotational speed are considered as parameters. The analysis is based on the bearing model of Raimondi and Boyd [1]. This model is generally valid for low-to-moderate speeds and a ratio of recess area-to-total bearing area of approximately 0.5 or greater. Design charts are presented for bearings having a ratio of recess area-to-total bearing area of 0.6 and employing capillary and orifice restrictors, these being the most common types of compensating elements. A design example is given to illustrate the use of the design charts.
