| It includes the analysis of the vibration movement of the ship's hull as an element. In this course, the ship's hull will be considered as a beam, and the additional water mass and additional water moments of inertia will be calculated first, and then the vibration analysis of the ship's hull in different modes will be taught. With the results obtained here, the effect of vibration sources on the body can be examined. |
