Method for reducing a vertical movement of a water vehicle

摘要

The method involves determining a vertical movement frequency range for a movement condition (x) of a water vehicle by determining a resonance frequency of vertical movement of the water vehicle, and partially determining whether the movement condition lies in the frequency range during driving of the water vehicle. A driving speed of the water vehicle and/or a route is changed by actuators till the frequency range drops, when the operating condition lies within the frequency range, where the actuators are controlled by actuator-controllers (7-9). An independent claim is also included for a device for executing a method for reducing vertical movement of a water vehicle.
