Method and arrangement of sensors for measuring the load on a bearing with rolling elements based on deformation model.

摘要

A method for determining a load vector acting on a rolling element bearing (1), wherein the method comprises: measuring displacement and / or strain using N sensors (8) for determining displacement and / or strain in a ring shaped element (5, 6, 7) of the rolling element bearing (1); determining a deformation of the element (5, 6, 7) by calculating amplitude and phase of N / 2 Fourier terms representing at least one form radially element shaped ring (5, 6, 7); feeding the N / 2 Fourier terms to a bearing neural network (12), wherein the neural network bearing (12) is trained to provide the load vector on the rolling element bearing (1) from the N / 2 Fourier terms.
