Advanced Engineering Vibrations for Electrical, Electronic and Mechatronic Designs (MS334)

SynopsisThis is a course of continuing education for working engineers in technical fields related to mechanical vibrations. It covers the fundamentals of engineering vibrations and then bridges to practical issues and solutions encountered in electrical, electronics, mechatronics and hard disk drive industries.

This course is intended for practicing engineers, reliability engineers and designers, and engineering managers concerned with practical aspects of dynamics and vibrations in engineering applications. The course will provide guidance and considerations relevant to the analysis and design of mechanical systems, complemented with the use of computer software tool with industrial case studies such as hard disk drive servo and mechanical designs. It also offers many examples of practical design solutions for different industrial problems.

This course places particular emphasis on building up strong analytical, numerical, and experimental technical skills on engineering vibrations. Upon completion of this course, participants should be able to appraise and address a wide range of vibration problems with a good insight.

The course instructor will draw on his extensive experience to illustrate the subject matter with practical examples from hard disk drive and turbomachinery industries.
