Fluctuation of Oil Film Pressure with Eccentricity and Waviness Considering Cylinder's Vibration

抄録

For the testing, a spring is fixed to one end of the plate for fixing a test cylinder, and the test cylinder is allowed to move up and down. If the test cylinder incorporates an eccentricity and a waviness, then the oil film pressure fluctuates and the test cylinder vibrates. We showed first the oil film pressure fluctuation and the cylinder's vibration by the numerical calculation, supposing that the waviness conforms to a sine curve. Then the experiment was done. The experimental values of the oil film pressure and the cylinder's vibration were compared with the values calculated considering the eccentricity and the waviness of the test cylinder.
