49323 Vibration Analysis
POSTGRADUATE COURSEWORK
 

Teaching school:

UTS:Engineering

Credit Points:

6

Modes of Presentation:

3hpw

Prerequisites:

 48660 Dynamics and Control (or equivalent) and 48642 Strength of Engineering Materials (or equivalent)

Description:

This subject extends students' understanding of vibration theory and its application to problems encountered in mechanical and structural engineering. It focuses on learning and practising the techniques and skills most frequently used in engineering practice. After a brief revision of basic vibration theory for single-degree-of-freedom systems, the subject moves on to multiple-degree-of-freedom systems, modal analysis, torsional vibration, approximation and numerical methods for transverse vibration including influence coefficient methods, transfer matrix method and finite element methods. Applications include vibration reduction by passive and active means, design of vehicle suspension systems, experimental modal analysis, powertrain dynamics, turbomachinery vibration and condition monitoring.

Contribution to Course Aims:

This subject will enhance the student’s professional knowledge and practical skills in solving vibration problems of mechanical and structural systems. The subject is suitable to the students doing sub-major of Mechanical Design and Analysis in program of mechanical engineering and the students doing other programs in the Faculty.

Content:

see above.

Method:

Half of the subject hours are for class lectures in three hour seminars or block release. Half of the subject hours are for assignments and a major project including computing and laboratory experiments. The subjects requires the use of Matlab and general purpose FEA programs in assignments and projects work.

Assessment:

 Assessment: Assignments and laboratory reports (70 per cent), final examination (30 per cent).
