A study on the Static and Dynamic Characteristics of Tilting Pad Thrust Bearing by Approximate Elasto-Thermohydrodynamic Lubrication Analysis

근사 탄성열유체윤활해석에 의한 틸팅 패드 트러스트 베어링의 정특성 및 동특성에 관한 연구

The thermohydrodynamic analysis of tilting pad thrust bearing is studied with the consideration of elastic effect of pad. Reynolds equation, deflection equation and energy equation are solved simultaneously with the boundary conditions. Reynolds equation is modified as the approximate form. Pads are supported by the line pivot and the point pivot respectively. Pads are considered as the flat planes. Effects of pad thickness on the performance of thrust bearing are emphasized and the performances of rigid pad and elastic pad are compared. Effects of inlet temperature on performances of the bearing are compared. Dynamic characteristics of both pad supported by line and point pivot are compared.
