Complex analysis of the vessel's shaft

The article considers the impact of operating loads on a ship's shaft. Preliminary static, dynamic, modal and harmonic calculations were performed in the finite element modeling environment. Data on the shaft's natural vibration frequencies, as well as load values in a given frequency range and structure deformations in the operating mode were obtained. A complex analysis of the ship's shaft has been carried out. Data on the frequencies of natural vibrations of the shaft, the values of loads in a given frequency range and deformation of the structure in the operating mode were obtained. According to the data obtained, it is possible to judge the change in the state of the structure during operation.
