Method for determining vibration behavior of ships during shipping operations, involves measuring oscillation frequency or period of oscillation of ship by known methods constantly or intermittently

摘要

The method involves measuring the oscillation frequency or period of oscillation of the ship by known methods constantly or intermittently. The oscillation frequency or period of oscillation of ship is calculated and displayed or recorded as a graph. The eigenvalues of frequency or period of the tank fluids in the ship are measured or calculated with known methods and displayed or recorded as graph constantly or intermittently. The oscillation frequency or oscillation period of ship is compared with the determined eigenvalues of frequency or period of the tank liquids in the ship.
