DIAGRAM OF THE RESONANT ROLL OF A SHIP IN IRREGULAR WAVES
The difficulty of manual calculation of pitching in the conditions of the bridge of the vessel on the basis of the current state of the theory of pitching is revealed. The possibility of further calculations of the conditions of resonant pitching. The equation of resonant pitching with the main parameters is given: apparent wavelength and eigenfrequency of vertical, pitching or onboard pitching. The resonance curves for several values of the eigenvalues of the pitching periods are constructed. The order of their use is given.
