Abstract Post switchgear of substation in a gale area is typical wind-sensitive structure. In order to reduce the wind-induced response post area, this paper, according theoretical formula optimal frequency ratio and damping TMD given by Den Hartog, tuned mass damper (TMD) proposed vibration first-order mode outside plane The Simulink simulation model simplified structure with established fluct...

This paper considers the use of a tuned inerter damper (TID) system for suppressing unwanted cable vibrations. The TID consists of an inerter, a device that exerts a force proportional to relative acceleration, coupled with a parallel spring and damper. It may be thought of as similar to a tuned-mass-damper, but requiring two terminals. As a two terminal device, the performance of the TID is co...

Impulsive loads and walking loads can generate problematic structural vibrations in flooring-systems. Measures that may be taken to mitigate the problem would often be to consider the implementation of a tuned mass damper or even more advanced vibration control technologies; this in order to add damping to the structure. Basically also passive humans on a floor act as a damping source, but it a...

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...
