Mechanical Vibration and Acoustic Noise - Analyses, Diagnostics and Attenuation (CS14-16-0)

SynopsisThis is a course of continuing education for working engineers in technical fields relevant to noise and vibration. It covers the fundamental theories and concepts before bridging to practical analysis and case studies, thus bypassing complex mathematical modelling and extended programming analysis.

This course is designed to help product engineers, reliability engineers and designers concerned with practical aspects of vibration diagnosis and acoustics of various engineering systems. The course will provide guidance relevant to equipment design, consideration on dynamics of vibratory systems, the use of computer software, and practical solutions for proactive maintenance improvement.

Moreover, it will emphasize understanding of the relevant phenomena and concepts in order to enable the participants to address a wide range of practical problems insightfully.

The course instructor will draw on his extensive experience to illustrate the subject matter with practical examples.
