Although we hardly interact with objects that are purely elastic or viscous, haptic perception studies of deformable objects are mostly limited to stiffness and damping. Psychophysical investigation of materials that show both elastic and viscous behavior (viscoelastic materials) is challenging due to their complex, time and rate dependent mechanical behavior. In this study, we provide a new in...

This study explores the optimal viscous damper size required to prevent a five-story building from colliding with rigid wall. It comprises two parts, both based on novel application of wavelet coherence method (WCoh). In first, impact incidents were estimated using WCoh method, and in second, an approach for optimizing was proposed. A validation model used verify proposed good agreement among t...

In this paper, we describe the design and manufacturing of a viscous inertial mass-damper (VIMD) prototype. The damper parameters, mass, damping coefficient can be continuously adjusted. Experimental validations were carried out on VIMD with various parameters scaled sagged cable 19.47 m long for vibration mitigation, along simulation study using finite element method (FEM). experimental result...

In recent decades, the dual systems of steel moment-resisting frames and RC shear walls have found extensive application as lateral load-resisting systems for high-rise structures in seismically active areas. This paper investigated the effectiveness of tuned mass damper (TMD), viscous damper, friction damper, and the lead-core rubber bearing in controlling the damage and seismic response of hi...

The simplest model possible for bouncing systems consists of a point mass bouncing passively on a mass-less spring without viscous losses. This type of spring-mass model has been used to describe the stance period of symmetric running gaits. In this study, we investigated the interaction between horse and rider at trot using three models of force-driven spring (-damper)-mass systems. The first ...
