Summary
A circular cylindrical liquid column changes under the influence of a steady axial micro-gravity field its static geometry into an amphora-type geometry. Under this influence the natural frequencies as well as the damped frequencies change with the magnitude of the axial Bondnumber. They are determined for such an amphora-type geometry for frictionless and viscous liquids. In addition the response of such systems to axial excitation is determined for various axial Bondnumbers. It was noticed that the natural frequencies decrease with increasing axial Bondnumber and that all vibration modes in the response show up for non-vanishing Bondnumber, whereas under pure xero-gravity only odd mode responses appear.
