Vibrating Loads Identification Using Inverse Acoustics in Fluid-Structure Interaction

Article Preview

Abstract:

In numerous engineering systems it is essential to know the vibrational behavior. Often laser vibrometers are used for vibration measurements. But this point should be considered that method utilization because of complex volume of source of vibration is difficult. To alleviate this problem several other methods were recommended such as Near Field Acoustical Holography and Inverse Numerical Acoustics. Vibrational properties knowledge helps in design, control and reduce undesirable vibration, but direct measurement is difficult and contain significant errors. The aim of this paper is the presentation of an efficient method using acoustics that can obtain vibrational properties by measuring other quantities, like fluid pressure dynamics somewhere near the structure. This procedure is based on inverse analysis that is more intricate than direct analysis.
