WitrynaThe LMS PolyMAX method is a further evolution of the least-squares complex frequency-domain (LSCF) estimation method. That method was first introduced to find initial values for the iterative maximum likelihood method [7]. The method estimates a so-called common-denominator transfer function model [8]. Quickly it was found that … Witryna16 paź 2024 · In this paper, 15 mode shapes in the frequency band 0 - 420 Hz are identified using the LMS PolyMAX solver. These modes represent the rigid bending modes in the z-direction and the torsion modes with respect to the longitudinal axis (x-direction). The specific telescopic wing structure can be approximately treated as a …
