Effect of model-form definition on uncertainty quantification in coupled models of mid-frequency range simulations
Mechanical Systems and Signal Processing(2017)
摘要
•Uncertainty quantification of coupled numerical models is pursued.•Analysis at the subsystem and coupled model levels is compared.•Methodology applied to a four-subsystem model to predict mid-frequency response.•Response is calculated using the Statistical Modal Energy Distribution Analysis.
