摘要
建立了导轴承性能热流体动力分析的数学模型，应用有限元法对表示油膜压力的Ｒｅｙｎｏｌｄｓ方程及表示油膜温度的Ｅｎｅｒｇｙ方程和表示温度和粘度关系的粘温方程进行了联立求解，获得了多瓦导轴承的瓦块压力分布，温度分布及其它轴承静态和动态参数。并根据这些参数对多瓦导轴承的性能作了分析，其结果对该轴承设计具有一定的指导作用，并对运行过程具有预测作用。
Mathmatical model of thermohydrodynamic (IHD) analysis of guide bearing in large thrust bearing is estabeished. the finite element method is used to solve the equations which are Reynolds equation, energy equation and temperature-viscosity equation. Fields about oil film pressure and film temperature and other parameters of the guide bearing are obtained. Finally, the performance of the bearing are analyzed by use these data. These conclusions can be used to design journal bearing and predict the running of the bearing.
