The main objective of this course is to introduce the basic concepts and analysis methods and

modeling of mechanical systems for vibration characteristics. It is also a key course for analyzing

systems having multiple degrees of freedom and continuous systems. It is aimed to provide the

students with the required knowledge and skills for modeling of systems and the different types of

vibrations and vibration measurements techniques
