Prerequisite

Baccalaureate degree in mechanical engineering or permission of instructor.

Course Description

In today's competitive environment every product designed by an engineer is subject to dynamic loads in sometimes harsh conditions. The product is likely to be more successful when vibration and noise performance of the design is optimized. This course provides a hands-on introduction to vibrations and noise engineering. The fundamental concepts of vibrations, noise, and acoustics are introduced. The characteristics of typical sensors and actuators used in dynamic testing, such as accelerometers, force transducers, strain gauges, microphones, mechanical shakers, and impact hammers, are reviewed. Using these sensors in combination with modern data-acquisition systems (LabView), students will learn to build experimental testing setups to measure the vibration and noise performance of typical engineering devices. Examples of practical applications are measurement of jet noise, measurement of vibration levels of devices, e.g. a ski, experimental modal analysis of structures, e.g., a golf club, and performing a noise control study of a machine. Several case studies encompassing contemporary design problems from industry are used in the classroom to enhance the learning process. The method of assessing students includes classroom participation, homework and laboratory assignments, examinations, and a final exam.
