Paper Abstract

A novel signal processing approach is developed in the present study for accurate evaluation of the output frequency responses of nonlinear systems to sinusoidal inputs. Simulation study is conducted, which verifies the effectiveness of the proposed approach. The approach is also applied to analyze the experimental data from dynamic testing of rheological properties of a polymer material. The result shows that the approach has a considerable potential to be used in a wide range of engineering applications.
