| Abstract: | This paper deals with the amplitude-frequency characteristic of a dumped oscillator with dry friction under a simple harmonic excitation. The averaging method is applied. Based on the equilibrium point analysis of the averaging equation, the amplitude-frequency characteristic equation is obtained. A numerical example is presented to compare the amplitude-frequency curves deduced from the averaging with those given by the direct numerical method. |
