Root mean square response of transducer systems to spectral density inputs
Abstract
Complex engineering systems are often subjected to significant vibration noise. In this analysis, an investigation is made into the general problem of the response of linear transducers to vibration noise inputs which can be characterized by power spectral density functions whose profiles can be partitioned into discrete frequency intervals. A generalized mathematical development is presented for evaluating the subsequent RMS (rootmeansquare) response of the system to a known input noisevibration power spectral density function. Specific consideration is given to examples of two transducer systems which can be characterized by a linear system transfer function. One is that of an accelerometer and the other is that of a linear differential transformer core rod.
