摘要

本文考虑油膜惯性与温粘效应，根据瓦块受力平衡方程，运动微分方程等，建立了挠性支承可倾瓦轴承动力学模型；提出一种挠性支承可倾瓦轴承的静平衡位置迭代计算方法，即基于PDE工具箱快速求解轴承非定常工况Reynolds 方程及二维能量方程，采用Newton-Raphson 迭代法可直接计算得到轴颈、瓦块静平衡位置。仿真结果与试验数据进行对比分析，验证了本文的动力学模型及仿真计算方法。

Abstract

The analysis includes the oil film inertia and viscosity temperature effects.Based on the pad force equilibrium equations and the differential equations of motion, the dynamic model of the flexible bearing tilting pad bearing is was established.In this paper, an iterative calculation method to determine the flexure pivot tilting pad that bears the static equilibrium position is was proposed.The PDE toolbox was used to solve the static and frequency disturbance pressure Reynolds equation The Newton-Raphson iteration method could be used to calculate the static equilibrium position of the journal and the pad.The simulation results were compared with the experimental data, and the dynamic model and simulation method are verified.
