本文件描述了一种比较箔片径向轴承性能测试结果的方法，该轴承由空气（气体）润滑，并由旋转轴旋转产生的气体动力支撑。本文件中提出的试验程序旨在预测和评估箔片径向滑动轴承的静载荷能力、摩擦系数和寿命，并比较不同试验条件下这些参数的结果，即不同尺寸的箔片轴承、轴的转速、周围环境的压力和湿度。 随着试验条件的改变，静载能力的大小可以根据试验设置而改变。 本文件中描述的试验方法具有以下应用范围。 a） 评估静载能力的标准是稳态条件；i、 e.该方法适用于有限的工作条件，具有均匀的量级、负载方向和转速。 b） 仅当箔片径向滑动轴承在任意转速下处于均匀转动惯量下时，才能应用评估程序。 c） 不考虑大小和方向随时间变化的动载荷。

This document describes a method for comparing the performance test results of foil journal bearings, which are lubricated by air (gas) and supported by the gas-dynamic force generated via the rotations of the rotating shaft. The test procedure proposed in this document aims to predict and evaluate the static load capacity, friction coefficient and lifetime of foil journal bearings and compare the results of these parameters under different test conditions, i.e. at varying dimensions of foil bearing, rotational speed of a shaft, pressure and humidity of the surroundings. The magnitude of the static load capacity can change according to the test setting, as the test conditions can be changed. The test method described in this document has the following application coverage. a) The criterion for evaluating the static load capacity is the steady-state condition; i.e. the method is applicable under limited operating conditions with uniform magnitude, load direction and rotational speed. b) The evaluation procedure can be applied only if the foil journal bearing is under a uniform rotating inertia at an arbitrary rotational speed. c) The dynamic load with time-variant magnitude and direction is not considered.
