Electric Machine Noise and Vibration. Noise and vibration in electric machines can cause both real and perceived failures in the performance and quality of a system driven by that electric machine. The noise can have structural (gear-slip, bearings, or other moving surfaces touching), aero-acoustic, load-induced or electromagnetic sources.

Fundamentals of Vibration - unife.it
The subject of vibration is introduced here in a relatively simple manner. The chapter begins with a brief history of vibration and continues with an examination of its impor-tance. The various steps involved in vibration analysis of an engineering system are out-lined, and essential definitions and concepts of vibration are introduced.
Noise, vibration, and harshness - Wikipedia
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks.While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via "jury" evaluations, or with analytical tools that can provide results reflecting human ...

lost (damper).The vibration of a system involves the alternating transfer of energy between its potential and kinetic forms. In a damped system, some energy is dissi-pated at each cycle of vibration and must be replaced from an external source if a steady vibration is to be maintained.Although a single physical structure may store
