Abstract

The design of five-pad tilting-pad journal bearings (TPJB) is complicated because of the uncertainty of design parameters which affects the performance of TPJB greatly. In this study, the numerical lubrication model is established to predict the performance of TPJB. Furthermore, a new optimal method combining the lubrication model and particle swarm method with a comprehensive target is brought out, which can obtain the optimal design parameters correctly and rapidly compared with enumeration method. The performance of TPJB is better after optimization, especially the temperature and frictional coefficient decreasing by about 31.1% and 35.8%, respectively. Moreover, different application scenarios of TPJB need different weight factor combinations in the comprehensive target, which is valuable for different design requirements.

基于粒子群的五垫倾垫滑动轴承设计数值优化

由于设计参数的不确定性极大地影响了五垫倾垫滑动轴承的性能，因此其设计十分复杂。在本研究中，建立了数值润滑模型来预测TPJB的性能。在此基础上，提出了一种结合润滑模型和粒子群法的综合目标优化方法，与枚举法相比，该方法能准确、快速地获得最优设计参数。优化后TPJB的性能较好，特别是温度和摩擦系数分别降低了约31.1%和35.8%。此外，TPJB的不同应用场景需要综合目标中不同的权重因子组合，这对于不同的设计要求具有重要价值。
