Vibration control method for parallel structures connected by damper and spring

Abstract

The purpose of this study is to analyze a simultaneous vibration control method of structures. The analyses are performed under the following assumptions: each structure is composed of a mass and spring and vibrates in a one-degree-of-freedom mode, and a vibration input is applied to the base of the structure. Here, the vibration model is composed of two structures connected by one damper and one spring in parallel. From the analyses, it was clarified that the theory of P, Q is useful as a method of optimum adjustment of this vibration control model. In addition, the optimum design procedure is described, the optimum values of tuning and damping parameters of this model are specified in graphical form, and the effectiveness of this method in reducing the transmissibility during resonance is shown to be considerably greater than that of the method connecting two structures by only a damper.
