In this the second part, the attention will he focused on the practical implementation of the techniques proposed in Part 1. Firstly, the problem of generating a periodic excitation signal with a specific spectrum in the experimental conditions will be solved by the use of a programmable signal analyzer. Secondly, using this spectral control technique and applying the generalized linear path identification method proposed in Part 1, two simple nonlinear structures are tested and analysed. Finally, the application of this new package of nonlinear system identification techniques is experimentally demonstrated on a multiple DOF structure. It includes the practical implementation of the spectral controller, the generalized linear path identification method, the practical location scheme of nonlinear elements and the in-situ nonlinear force state mapping technique.
