In this paper the forced vibrations of a system with the restoring force which is expressed as a function of displacement and time is treated theoretically and experimentally. The equation of motion of a single-degree-of-freedom system is expressed as follows : [numerical formula], where m is mass, x is displacement, t is time, c is viscous damping coefficient, A_1,E_1,B_1 are characteristic coefficients of the restoring force, and mrω^2cos (ωt+φ_0) is external force. We solved the equation on the assumption that the steady vibration is approximately expressed as x=x_<max> cos (ωt-φ_0), and the results were confirmed by suitable experiments. Moreover we discussed on the stability of the solutions theoretically.
