В статье представлена обобщенная схема вычисления ускорений в произвольной точке судна в инерциальной и связанной с судном системах координат при известных параметрах его качки. Предложена практическая формула расчета ускорения в точке судна с учетом влияния гравитации при моделировании качки судна на нерегулярном волнении в частотной области. Произведен сравнительный анализ амплитуд и форм колебаний вертикальных и поперечно-горизонтальных ускорений в произвольной точке судна при их расчете по точным и приближенным формулам. В статье описаны основные современные критерии мореходности, использующие в качестве основы ускорения в характерных точках корпуса судна, и позволяющие количественно оценивать воздействие качки на плавсостав.

The article presents a generalized scheme for calculating accelerations at an arbitrary point of the ship in the inertial and fixed to the moving ship frames of reference with known parameters of its motions. A practical formula for calculating the acceleration at any ship's point has been proposed, taking into account the influence of gravity when modeling the motion of a ship in irregular waves in the frequency domain. A comparative analysis of the amplitudes and modes of oscillations of vertical and transversal accelerations at an arbitrary point of the ship have been made where they were calculated using exact and approximate formulae. The article describes the main present seakeeping criteria using acceleration at characteristic points of the ship's hull as a basis, which allow for quantifying the impact of ship motions on the crew and passengers.
