This paper deals with the vibration of a two-degree-of -freedom system with linear and nonlinear restoring forces, and with the Coulomb friction between one mass and the base which vibrates harmonically. These methods are used in this analysis, that is, the analytical method using boundary conditions in the interval of a half period, a direct numerical integral method, and the one using equivalent viscous damping which is usually used as the approximation of Coulomb friction. The first method is applied to the solutions of vibrations with two stops within a half period and the second one is improved to reduce the calculation time. From the first and the second methods, it turns out that the value of the dimensionless Coulomb friction is higher than that expected from the third method to minimize the vibration of the other mass far from the base.
