摘要
建立了考虑瞬态油膜压力影响的热稳定性分析模型 ,用求解系统周期解分岔的 PNF法对推力轴承系统的热稳定性进行了研究 ,结合 Poincare映射与胞映射法思想 ,提出了用于分析系统周期稳态解全局特性的数值计算 PCM方法 。
The model of the thermal system of the thrust bearing considering the effect of transient pressures is established. The PNF method for investigating the bifurcation of the periodic solution of the system is used to study the thermal stability of thrust bearings. A new numerical method called PCM(Poincare-Cell-Mapping)is presented to investigate the global stability of the periodic solution of the thermal system of thrust bearings.
