Calculation of Natural Frequencies and Normal Modes of Vibration for a Compound Isolation Mounting System.

摘要

The natural frequencies and normal modes of vibration of a compound mounting system are determined. The system consists of an assembly supported by a set of isolation mountings carried by a cradle which is, in turn, supported by another set of isolation mountings attached to the hull of a ship. The dynamical equations of motion of the system and the numerical solution of a specific example are given.
