Behavior of the system under sinusoidal excitation in the vicinity of the resonant frequency of the tube (V = 1.3 V). Blue: U, red: Q. Top left: normalized experimental time responses. Top right: the numerically determined time responses using the parameters identified from the HBM. Bottom: the temporal responses determined numerically using the parameters identified from the CX-A method. Configuration 1: h_m = 0.23 mm, R_m = 5 cm, f_m = 45 Hz. (a) Measured time responses. (b) The numerically determined time responses using the parameters identified from the HBM. (c) The numerically determined temporal responses using the parameters identified from the CX-A method.
