Oscillations and Machine Dynamics

The course "Vibrations and Dynamic Machine" consists of two parts. The first part refers to the oscillating dynamic systems with one degree of freedom and second on the oscillation of discrete dynamic systems with two or more degrees of freedom. The structure and contents of the course formed ον the basis of the educational experience of the author and course content as it taught in respective Departments in Greece and abroad. An effort was made to each section of the course to describe the details in order the basic principles to be illustrated as possible. So the student is able to understand the way that addresses the key problems of the oscillating systems.

Objectives

After successful completion of the course students should: • studying vibrations of simple and composite mechanical systems • talantontiki to model the behavior of mechanical systems • to solve the equations of the mathematical model describing the oscillatory behavior of a mechanical system • be able to conduct measurements of various physical quantities oscillatory mechanical systems to generally draw conclusions through graphical and / or computational treatment of measurements to assess the quantitative accuracy of the final results and to prepare the relevant technical report
