Local polynomial method for frequency response function identification
Systems Science & Control Engineering, 2020 Here we propose the local polynomial method to solve the problem of estimating the frequency response function in the linear system. Compared with other nonparametric identification methods based on the windowing strategies, this new identification ...

FREQUENCY RESPONSE FUNCTION STATISTICS OF DIFFUSE SYSTEMS
Inter-Noise 2022, 2023 Vibro-acoustic analysis at high frequencies is challenging due to a large sensitivity to spatial variations and short acoustical wavelengths, rendering deterministic methods expensive. At these frequencies, the wave field is usually assumed diffuse. A realization of a diffuse field can be obtained considering that the mode shapes of the system are ...

A two-stage model updating method for the linear parts of structures with local nonlinearities
Frontiers in Materials, 2023 Finite element model updating provides an important supplement for finite element modelling. However, some studies have shown that if the tested structure involves local nonlinearities due to damages, material properties and large deformation et al., it ...
