VIBRATION TESTS OF 1-STORY RESPONSE CONTROL SYSTEM USING INERTIAL MASS AND OPTIMIZED SOFTY SPRING AND VISCOUS ELEMENT
The previous study have already proposed optimum response control method of 1-DOF system using linear viscous damper with rotational inertial mass and linear spring, and substituting equivalent linear Kelvin system for original system to develop simplified analysis and design procedures for practical applications. To achieve optimum control, we used the optimum design theory of the dynamic vibration absorber or the tuned-mass damper proposed by Den Hartog1). In his theory, optimum design is achieved by minimizing the peaks of the resonance curve of the system. In this paper, we discuss proprieties of the optimum response control theory for magnification factor of displacement and acceleration. This paper also validated the tuning factor of substituting equivalent linear Kelvin system, and response damping ratio of the optimum control system subjected to random excitations.
