TLD is a tank filled with water and serves as a dynamic vibration absorber for passive control of structures. This paper addresses the comparisons of TLD performances corresponding to different tank geometries including rectangular and conical shapes. Due to the importance of water and tank weight as a load on top of a building, volume is considered to be a constant parameter in this study. Fir...

In this paper, a radically new concept of Stiff Seismic Base Absorber (SBA) is proposed for seismic protection multistory building structures. An inerter first implemented, connecting directly the structure to ground. This results in decrease natural frequency structure, without decreasing its structural stiffness. Parallel, negative stiffness-based absorber used increase apparent damping behav...

This work is devoted to the creation of a mathematical model transverse vibrations plate and liquid section dynamic absorber. Mathematical was developed using bond graph methodology estimate hysteresis type elastic dissipative characteristic in conjunction with The reliability demonstrated by origin several specific models from special cases. demonstrates ability dynamics protected vibration de...

Abstract. To absorb the vibration of car body high-speed train in multiple degrees freedom, a multi-degree freedom dynamic absorber (MDOF DVA) is proposed. Installed under body, natural frequency MDOF DVA from each DOF can be designed as for every single degree body. Hence, 12-DOF model including main system and an established, principle Multi-DOF absorption analyzed by combining design method ...

To compute dynamic characteristics of nonlinear viscoelastic springs with elastic structures having huge degree-of-freedom, Yamaguchi proposed a new fast numerical method using finite element method [1]-[2]. In this method, restoring forces of the springs are expressed using power series of their elongation. In the expression, nonlinear hysteresis damping is introduced. In this expression, nonl...
