On the Houde Damper for a Damped Vibration System

This paper treats analytically the vibration prevention effect of the Houde damper which is attached to a main vibration system with positive or negative damping. Analyses about the damper of this type been done in the past only in the cases of a main system without damping. In this paper, the analyses are done both in the case of the main system with negative damping, that is a self-excited vibration system, and in the case of the main system with positive damping which is subjected to various alternate disturbing external forces. It is shown that better effect can be obtained in each case, if the optimum value of damping is given to the Houde damper with consideration of the damping of the main system.
