...S. Zahra Mikaeeli; Cyrusi Aghanajafi Purpose Optimization and thermohydrodynamic analysis of five-pad tilting pad journal bearing. Design/methodology/approach The multi-objective particle swarm optimization method is used to enhance performance of thermal hydrodynamic tilting-pad journal...

... on static and dynamic characteristics of tilting pad journal bearings were analyzed in depth. Findings The operating conditions have a strong effect on the static properties of the bearings. The dynamic characteristics of the TPJB were the most influenced by the shaft speed. The effects of the load...

...Zhiming Zhao; Feng Ji; Yongsheng Guan; Xiaoyang Yuan Purpose High power rotating machinery requires large diameter bearings that can perform under extreme conditions. Vibrations and critical speeds of rotor supported by tilting pad journal bearing (TPJBs) exceeding their design limits may cause...

... and c₂ represent the preload coefficient of the tilting pad. The relationship between c₁and c₂ and the preload coefficient of the tilting pad m is shown as follows: (1) m = 1 - c 1 c 2 Tilting pad journal bearing...
