GEM 409 - Ship Vibrations

Course Objectives

1.To understand the key concepts, ideas, and fundamental principles of structural vibration.
2.To transform engineering problems with a dynamic context into representative models, which are realistic enough, yet suitable for analytical treatment.
3.To perform vibration analysis of structural systems and study their dynamic behavior.
4.To describe dynamics of continuous systems in terms of multi-degrees-of-freedom systems, study their vibration, and evaluate resulting performance.
5.To apply numerical solution techniques to vibration problems.
6.To study the vibration of ship structures considering different types of excitations.
7.To perform frequency domain vibration analysis of ship structures.
8.To improve programming skills for engineering computation and understand the significance of using modern computational tools for solution of engineering problems.
