Abstract：The single-degree-of-freedom system with nonlinear energy sink is modeled, and the finite difference method is used to solve the numerical solution. Then the Monte Carlo method is used to simulate the system. The steady-state statistical response of the system obtained by two different methods is compared. The parameters discussion and analysis are carried out, and the influence of different parameters on the steady-state statistical response of the system is discussed, which provides a reference for the design of nonlinear energy sink dynamic parameters under random excitation.
