This paper deals with the analyses of response displacement of forced vibrations for harmonic and superharmonic vibrations in piecewise-linear systems with damping, and gives a stability analyses for periodic solutions utilizing calculus of variations. Following these theoretical analyses, the numerical calculations are performed, and the resonance curves are constructed using the resulting vibrations. Next, the stability charts for resulting vibrations are constructed by numerical calculation. The stability criterions for periodic solutions on steady vibration are discussed utilizing their charts. By using this charts, the stable branches for the resonance curves are distinguished with the unstable ones. For verification of the analytical method, the experiments are also performed. And comparing the theoretical results with the experimental ones, it is shown that they show a fairly good agreement.
