• Forced vibrations of a concentrated-mass continuum system with an impact-body are discussed. The impact-body moves in a groove of the concentrated mass and strikes the concentrated mass at opposite ends of the groove. Periodic solutions of the system excited by harmonic motion of a fundation are presented, and their stability is discussed. This paper treats only such periodic motion that during n periods of harmonic motion of the foundation two impacts occur at equal time intervals and at opposite ends of the groove (n : odd). The equation of motion is written in the form of a partial integro-differential equation by the use of an influence function. As an example, numerical calculations are carried out for the simplest system. That is, the continuum of this system is a uniform coil spring. Stability regions are determined and maximum displacements of the concentrated mass are calculated. The results show that the damping effects of the impact-damper are sufficiently good.
