In this paper, a numerical process is presented for predicting the response of vibrating structures excited by a non-homogeneous turbulent boundary layer. This one is based on the synthesis of different realizations of the random pressure fluctuations that can be introduced as loading of a vibroacoustic model. The vibratory response is finally dedu...

... the other hand, Fig. 5(b) shows the results for the G-UWPW method that supposes identical wall plane wave phases for the different sub-areas. The resulting pressure field is spatially continuous, even through the sub-area boundaries, that is consistence with the physic of the TBL. The intensity of the pressure is still increasing along the ❸ x ...

... does not appear explicitly in this last formulation and the pressure can vary from one node to another, the process related to Eq. (28) is named the "continuously" varying uncorrelated wall plane waves (C-UWPW) technique. For illustration, Fig. 12 presents two realizations of the WPF synthetized with the C-UWPW for the same situation than Fig. 5. The WPF varies well continuously and the strength is growing gradually from the leading edge to the trailing ...

The distributed acoustic sensing system can obtain the vibration signal caused by the vibration of the train. By analyzing these wheel-rail vibration signals, an abnormal wheel-rail relationship identification scheme is proposed. The variational mode decomposition is employed for signal decomposition, thereby obtaining intrinsic mode functions with...
