【Abstract】 On the basis of a single-DOF vibration system with symmetric gap,an simulation model with a full equivalent mathematical model was designed using various submodule in the module library of Simulink. The model consisted of integral module,nonlinear module,output module,can realize the output of the system steady-state response phase diagram,results accord with the results of numerical analysis. This method provides a new simulation method for studying the dynamic behavior of the nonlinear system.更多还原
