Fundamental Research on Hydrostatic Bearing utilizing the ER Effect of Liquid Crystal
Details
In this research, we utilize the ER effect of liquid crystal to the lift and height control of a flat plate on radial flows as a fundamental test to the application of liquid crystal to hydrostatic bearing. The electric field was applied to the radial flow between the lifted plate and electrodes. Rectangular pulse wave with controlled duty ratio was employed to adjust the apparent viscosity of liquid crystal. We found that our method was useful to the height and parallelism control of the lifted plate and the lift obtained in the experiment was in good agreement with the estimation from ER effect of liquid crystal.
