Abstract:This paper investigates the nonlinear dynamic response of a single-degree-of-freedom mass-spring system. The experimental modal analysis is carried out by three typical types of spectral testing which are burst random, sine testing and periodic chirp excitation to achieve the objective of this study. The experimental data from the burst random excitation is used to identify the natural frequency of the system. The nonlinear dynamic response of the system is detected by means of using the sine testing and perio… Show more
