Abstract EN
This paper is to be submitting an identification method for the unbalance parameters of a rotor-bearing system.
In the method, the unbalance parameters identification problem is formulated as the unbalance force reconstruction which belongs to solving deconvolution problem, in which the unbalance force is expressed in the time domain.
The unbalance response is expressed by the convolution integral of Green’s function and the unbalance force.
In order to avoid the unstable solution arising from the noisy responses and the deconvolution, a regularization method is adopted to stabilize the solution.
Meanwhile, a searching of the sensitive measured point has also been carried out to confirm the robustness of the method.
Numerical example and a test rig have been used to illustrate the proposed method.
