The rotational frequency response function (RFRF) plays a crucial role in increasing the accuracy of calculated results frequency-based substructuring method. However, RFRFs are often omitted due to difficulties measurement process and limitations equipment. This paper presents scheme estimating FRF an irregular plate structure using FE model reduction expansion reduced was introduced improved ...

For most force measurement applications, the strain gage based transducer can be relied upon to faithfully convert a mechanical input into a proportional electrical analog output signal. However, when the mechanical input is either applied or changes at a rapid rate, the sensor may distort the conversion and the user should be aware of the possible consequences of this distortion. This article ...

A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model. The complex plane investigation renders some important inequality cons...
