用在高速转子轴承系统中的挤压油膜轴承,又称挤压油膜阻尼器,其运转条件上的高速、主要承受旋转载荷、乃至冲击载荷、以及轴承对系统振动强烈反响等力学特点,导致了对它的油膜润滑理论计算具有一些相应的特点。本报告介绍了如下的相关算法:要求既快又准的雷诺方程解法;要求能够计及供压效应;要求能够计及润滑油膜中的液-气二相流效应。
Used in high-speed rotor bearing system of squeeze film bearings, also known as squeeze film damper, the operating conditions of the high-speed, mainly to bear the rotating load, and even the impact load, as well as the strong reaction of the system bearing vibration and other mechanical characteristics, resulting in Its oil film lubrication theory has some corresponding characteristics. This report describes the following algorithms: Fast and accurate Reynolds equation solutions are required; requirements for supply pressure effects are accounted for; requirements for liquid-vapor two-phase flow effects in lubricant films are taken into account.
