MEC 4305 - Vibration  Analysis  II

Credits:   4 
Lectures/Tut.:   2 hr/wk 
Labs:  3 sessions 
Prerequisite:  MEC 3304

Objectives
The unit covers mechanical vibration analysis of multi-degree of freedom discrete systems using matrices and other numerical methods for finding their dynamic response. Vibration of continuous system having single degree of freedom and practical applications of vibration control shall be dealt with.

Syllabus

·  Torsional oscillations of two and three rotor systems. Stepped shafts, equivalent lengths and location of nodes. Referred stiffness and inertia. Analysis of geared systems.

·  Analysis of free, damped and forced multi degree of freedom systems. Matrix analysis using the characteristic equation and the power iterative method. Dynamic,  stiffness and flexibility matrices. Complex amplitude and mechanical impedance. Field and Point matrix. Transfer matrices. Vibrations of continuous medium,  Langargian Equations.
