| The technique for determination the hydrodynamic coefficients of equations of motion of solid body with cavity of rectangular parallelepiped shape by its transverse motions is suggested. This technique for solving basic boundary problems is based on the modified method of cojugation of solutions and takes singularities in first derivatives of sought-for functions on the edges of cuts into account. The analysis of effectiveness of algorithm and some numerical results of calculations of frequences and associated masses of liquid in cavity under consideration is represented. |
