Abstract
Vibration with collision has widely utilized on industrial techniques, especially in the fields of impulsive working, impact machining and parts assembly, because its generated impact force has impulsive property, the very high peak and a short impact time. Hence, a tool can easily work with very high level of the force in the working, and parts can be given a positioning of the high accurate resolution to the specified position by the force which can be easily over the maximum friction force and can't move only the short distance according to the short impact time. The impact is generated between an impacter of one degree of freedom vibratory system and the impact follower of the first order lag system with a mass and a damper. The paper deals analytically with characteristics of a steady-state repetitive impact motion which has the period agreed with one of a harmonic excitation force for many industrial utilities. The impulse, impact intensity is proportional to the pressure force level required to support the follower. In the specified condition, the modal of the impacter approaches that of an impact system having a rigidly fixed follower, a wall.
