  • Quantification of bias errors influence in frequency based substructuring using sensitivity analysis [Elektronski vir]
    Čepon, Gregor ...
    The methodology to divide complex systems into several subsystems is a common practice in the field of structural dynamics. Structural dynamic analyses can be carried out more efficiently if ... subsystems are analysed separately and later coupled using dynamic substructuring techniques. However a reliable experimental application of frequency based substructuring (FBS) remains a challenge as it requires highly accurate acquisition of subsystems’ frequency response functions (FRFs). Even a small error from the measurement campaign can yield erroneous coupling results. The measurement errors can be either random or systematic, with the latter often referred to as bias. Impact excitation is popular in dynamic substructuring due to the fast FRF calculation for each impact location. However, deviations in the location of excitation as a typical example of measurement bias affect the FRFs throughout the whole frequency range.
