THEORETICAL INVESTIGATION OF THE DYNAMIC BEHAVIOR OF THE MERCURY DAMPER

Abstract

The dynamic behavior of the mercury damper is investigated. Particular attention is paid to the eccentric annular mercury configuration, which is the final continuous ring phase which occurs in the operation of all mercury dampers. In this phase the damping is the poorest, and the system is closely linear. The crescent, or broken-ring, case is also considered. During the course of the investigation the hydrodynamic problem is treated as three dimensional, and extensive use is made of a variational principle of least viscous fractional power loss, which is derived. A variational principle of least constraint is also used to advantage. Formulas for calculating the behavior of the mercury damper are obtained.
