One transducer method for quantifying vibration power flow in orthotropic plates for both general and far-field conditions

Frequency response function technique is used to quantify a vibration field in orthotropic plates considering both general-field and far-field conditions. If vibration field is stationary, one transducer technique using frequency response function (FRF) is an alternative to conventional structural intensity measurements. It is free from finite difference and phase mismatch errors that occur during data acquisition.In this paper, one-transducer technique using FRF is employed to formulate a structural intensity field in the frequency domain without the usage of finite difference approximation. As a result, one transducer may be employed sequentially to quantify the vibration fields.
