MECHANICAL ENGINEERING TRACK(S):  Engineering Mechanics

 

Catalog Description

 

The treatment of vibration fundamentals including free, damped and forced harmonic vibrations of linear single and multi-degree of freedom systems, modal analysis, continuous systems and a practical project.

Course Objectives

 

To introduce students to a combination of traditional and state-of-the-art mechanical vibration theory and methods, and their application to real world engineering. To be successful at these objectives, each midshipman must demonstrate the following outcomes:

 

• Students will demonstrate the ability to analyze the free motion of simple continuous systems.

 

• Students will demonstrate the ability to analyze wave motion in strings, rods, shafts and beams.

 

• Students will demonstrate the ability to analyze the free and forced response of a single degree of freedom mechanical oscillator, and apply the work to real world engineering examples.

 

• Students will demonstrate the ability to analyze and design a tuned vibration absorber.

 

• Students will demonstrate the ability to analyze discrete mass/spring systems and determine natural frequencies and mode shapes, both analytically and experimentally.

 

• Students will demonstrate the ability to work in groups.

 

• Students will demonstrate the ability to communicate effectively in both the written word and by oral presentation
