Random vibration of a nonlinear two-degree-of-freedom oscillator. [Pipe system behavior during rupture and blowdown]
An analytical and experimental investigation is made of the dynamic response of a nonlinear two-degree-of-freedom oscillator that models some of the basic phenomena involved in the response of complex nuclear power plant systems under dynamic environments. An approximate analytical solution is obtained for the stationary response of the system when subjected to stationary random excitation. Experimental measurements performed with an electronic analog computer and numerically simulated solutions generated by means of a digital computer verify the findings. Results are given for the power spectral density and root-mean-squared level of the response. The effects of various system parameters on the response of the nonlinear system are determined.
