Analysis Digital Calculations Of Natural Frequencies, Vibration Patterns And Power Density Spectrum Drawing For Real Ship Propulsion Station

Abstract

This research designed a real propulsion system for a real ship with its core components using an engineering design software that adopts digital methods and then calculates the natural frequencies of vibration and approval for external loads. The vibration patterns approved for these frequencies were also drawn and predicted the way the rotating blocks would vibrate around the rotation level in case of movement as well as the angle of the elephant was calculated along the rotor column by calculating vibratory displacement in the vertical direction on the rotation container that is determined by its comparison with the permissible values the stressful state of the power transfer column as well as the special curves of the vibratory spectrum density of both stress and inflammation cases and the identification of frequencies accompanied by maximum stress and effectiveness power as well as an algorithm has been developed as sequential steps to calculate natural frequencies and intensity patterns. The energy intensity was curved using SolidWorks, and the vibratory response to vibration acceleration was drawn at the start of takeoff in order to compare the great value with the values allowed by the BRC. The relationship between the frequency at which the system operates with the great angle of the elephant as well as the great stress has also been inferred, and recommendations have finally been made for consideration during simulation using SolidWorks and recommendations for future research work.
