In a previous paper, the authors proposed a nonparametric Identification technique of nonlinear multi-degree-of-freedom systems. Theoretically, the technique can be applied to systems with any number of degrees of freedom, but it has been found that in practical cases the technique is difficult to apply to systems with larger degrees of freedom. The reason is that the unknown parameters for a system become vast as the degrees of freedom of the system become larger. In this paper, an improved technique is proposed which not only requires fewer unknown parameters, but also is more convenient for use in succeeding analysis. Numerical simulation is conducted, and applicability of the improved technique is shown. Furthermore, its advantage in succeeding analysis is demonstrated by applying the identification results to the incremental transfer matrix method.
