Pressure distribution of the liquid crystal journal bearing

Abstract

This paper describes the properties of the journal bearing using liquid crystal (LC) as a lubricating oil in order to realize the real-time control of the hydrodynamic lubrication characteristic. The change of pressure distribution in applying the voltage to LC was required by the theoretical calculation. We focused on the position where the voltage was applied and examined the effect of the position on the pressure distribution, eccentricity and attitude angle. The results showed the optimum location of electrode to effectively change the pressure distribution and position of journal center.
