| Abstract: | Using numerical method the nonlinear chracteristics of response for the single degree of freedom of parametric vibration system without damping under single frequency stiffness and outer excitations is studied in this paper. It is shown that some important characteristics of parametric vibration system including (1) single frequency excitation leads to multi frequencies response; (2) some special frequency distributed states are found and (3) the response of system shows multi frequencies resonant phenomenon. |
