Thermohydrodynamic Lubrication Analysis of High Speed Journal Bearing Considering Variable Density and Specific Heat: Part II - Shaft Misalignment Effect

변화하는 밀도와 비열을 고려한 고속 저어널 베어링의 열유체 윤활해석 II-축 경사도 영향

Within some degree of journal misalignment, maximum pressure, maximum temperature, bearing load, friction and side leakage in high-speed journal bearing operation are examined under the condition of variable density and specific heat. The results are compared with the calculation results under the conditions of constant density and specific heat, and variable density and constant specific heat. It is found that the effects of variable density and specific heat on shaft misalignment are significant in determining the load capacity of a journal bearing operating at high speed.
