Effect of Gyroscopic effects on spindle-bearing systems

2001-04-26 org.kosen.entty.User@54971082 박상범(simon1031)

Gyroscopic effects are due to the coriolis acceleration exerted on the bearings which result in skew matrix in velocity. I would like to know how this effect would affect spindle bearing dynamics? (i.e., decrease of stiffness, natural frequencies (?)) Any papers on this topic? Thanks Simon parks@mech.ubc.ca

    Here is a paper you can take a look. In that paper, you can also find references. Wang, S. and Yi, K., "Coupled Vibration Analysis of HDD Spindle System Using the Finite Element Method," 7th International Congress on Sound and Vibration , pp. 2123-2130, Garmisch-Partenkirchen, Germany, July 2000 >Gyroscopic effects are due to the coriolis acceleration exerted on the bearings which result in skew matrix in velocity. > >I would like to know how this effect would affect spindle bearing dynamics? >(i.e., decrease of stiffness, natural frequencies (?)) > >Any papers on this topic? > >Thanks > >Simon >parks@mech.ubc.ca > >
