摘要

为准确预测挤压油膜阻尼器空化流场特性，基于ANSYSFluent软件建立非同心型挤压油膜阻尼器三维非定常空化流场求解模型.分别采用Zwart-Gerber-Belamri（Z-G-B）、Schnerr-Sauer(S-S)及Singhal三种空化模型计算得到挤压油膜阻尼器各测点的压力结果，并将其与实验数据进行对比，比较了三种空化模型下阻尼器内的油膜压力与气穴分布、流场中的气穴比以及油膜力特性.结果表明，三种空化模型中S-S模型的数值结果与试验数据最为吻合，适用于描述挤压油膜阻尼器空化流场特性，为挤压油膜阻尼器空化流场模拟提供了可靠的模型和方法.

Abstract

In order to accurately predict the cavitation flow field characteristics of the squeeze oil film damper, a three-dimensional unsteady cavitation flow field solving model for non-concentric squeezed film dampers was established based on ANSYS-Fluent software. Three kinds of cavitation models of Zwart-GerberBelamri (Z-G-B), Schnerr-Sauer (S-S) and Singhal were used to calculate the pressure on observing points of the squeeze film damper，and to compare with the experimental data. Furthermore, the oil film pressure and cavitation distribution, cavitation ratio in the flow field and oil film force characteristics were compared for three cavitation models. Results show that the numerical results of S-S model are in good agreement with the experimental data, which can be used to describe the cavitation flow field characteristics of squeeze film damper, which provide a validated model and method for the simulation of cavitation flow field of squeeze film damper.

Key words： squeeze film damper; cavitation model; oil film pressure; vapor volume fraction; cavitation radio
