本文件规定了多波瓣和可倾瓦径向滑动轴承计算的一般原则、假设和前提条件，该计算程序基于大量简化假设，易于使用。为了可靠地评估这种计算方法的结果，必须考虑这些假设的物理意义以及实际经验，例如在实际操作条件下对实际机械进行的温度测量。从这个意义上讲，本文件提供了一种简单的方法来预测滑动轴承的近似性能，适用于那些无法获得更复杂和更准确的计算技术的人。该计算方法用于设计和优化滑动轴承，例如涡轮机、压缩机、发电机、电动机、齿轮和泵中的滑动轴承。它仅限于稳态运行，即在连续运行状态下，根据大小和方向以及转子角速度的负载是恒定的。不记录不稳定的工作状态。ISO/TS 31657-2和ISO/TS 31657-3中指出了线性振动和稳定性研究所需滑动轴承的刚度和阻尼系数。

This document specifies the general principles, assumptions and preconditions for the calculation of multi-lobed and tilting-pad journal bearings by means of an easy-to-use calculation procedure based on numerous simplifying assumptions. For a reliable evaluation of the results of this calculation method, it is indispensable to consider the physical implications of these assumptions as well as practical experiences for instance from temperature measurements carried out on real machinery under typical operating conditions. Applied in this sense, this document presents a simple way to predict the approximate performance of plain journal bearings for those unable to access more complex and accurate calculation techniques.The calculation method serves for the design and optimisation of plain bearings, for example in turbines, compressors, generators, electric motors, gears and pumps. It is restricted to steady-state operation, i.e. in continuous operating states the load according to size and direction and the angular velocity of the rotor are constant.Unsteady operating states are not recorded. The stiffness and damping coefficients of the plain journal bearings required for the linear vibration and stability investigations are indicated in ISO/TS 31657-2 and ISO/TS 31657-3.
