Method and sensor arrangement for determining a load vector acting on a rolling element bearing ( 1 ) in operation. A plurality of N sensors ( 8 ) are provided which measure displacement and/or strain for determining displacement and/or strain in one of the elements ( 5, 6, 7 ) of the rolling element bearing ( 1 ). Furthermore, a mode shape coefficients calculator ( 11 ) is provided, connected to the plurality of N sensors ( 8 ), for determining a deformation of the element ( 5, 6, 7 ) by calculating amplitude and phase of N/2 Fourier terms representing at least one radial mode shape of the ring shape element ( 5, 6, 7 ). Also, a bearing neural network ( 12 ) is present, connected to the mode shape coefficients calculator ( 11 ), the bearing neural network ( 12 ) being trained to provide the load vector on the rolling element bearing ( 1 ) from the N/2 Fourier terms. |
