This course is a general introduction to vibration with a focus on practical application in a variety of engineering systems. Components, systems, and structures typically experience vibration at some time in their life, either during manufacturing, transport, or service. They also have critical frequencies at which they naturally vibrate that should be avoided in all situations throughout their design life.
Several methods and examples of calculating natural frequency are presented with a discussion of how modes are and are not excited. This concept is then extended to the free vibration response of an excited system, and a comparison of undamped, damped, and critically damped motion is made. Harmonic motion and forced vibration motion of real damped systems and the resulting potential fatigue failures are discussed.
Due to the complexity of most systems, the natural frequency and vibratory response calculations are either very difficult or impossible. The use of finite element analysis (FEA) for modal and harmonic analysis is common, and a discussion of these methods is presented. The use of FEA can be very helpful in avoiding natural frequencies and vibration fatigue in new designs and in problem-solving for existing designs that are experiencing failures. Another option for evaluating existing designs is the measurement of vibration data to find the root cause of the failure, and measurement methods, as well as data analysis tips, are presented with problem-solving in mind.
Finally, options for improving designs that are experiencing resonance or other vibration problems are presented. Examples of useful vibration in designs are also given. After reviewing this course, the engineer will be aware of problems that can arise in their design due to vibration and how to improve existing designs that are experiencing issues caused by vibration.
