Vibration Control of a Power Transmission Tower with Pounding Tuned Mass Damper under Multi-Component Seismic Excitations
In this paper, the two-dimensional vibration controls of a power transmission tower with a pounding tuned mass damper (PTMD) under multi-component seismic excitations are analyzed. A three-dimensional finite element model of a practical power transmission tower is established in ABAQUS (Dassasult Simulia Company, Providence, RI, USA). The TMD (tuned mass damper) and PTMD are simulated by the fi...
متن کاملVibration Control of Structures with Initially Accelerated Passive Tuned Mass Dampers under Near-Fault Earthquake Excitation
This article deals with the applicability of passive tuned mass damper (PTMD) for reducing the dynamic responses of structures under near-fault earthquake excitations. Three types of pulse-like time functions are employed to simulate the near-fault ground motion. The vibration control effectiveness of PTMDs is extensively investigated through the comparisons of response spectrum and response ti...
متن کاملthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولdesign and performance evaluation of tuned vibration absorber for the vibration control of a centrifugal pump
with the prolonged use of domestic centrifugal pump, due to erosion, corrosion and an unbalance the sever vibration of the pump are resulted. an erratic sound coming out of pump makes the user uncomfortable. here, tuned vibration absorber (tva) is used as a vibration controlling device. it is designed to reduce the rms velocity below 20% of the circumferential speed, at which the impeller is ba...
متن کاملThe effect of time delay on control stability of an electromagnetic active tuned mass damper for vibration control
The aim of this paper is to investigate the effect of time delays on the stability of a zero-placement position and velocity feedback law for a vibratory system comprising harmonic excitation equipped with an electromagnetic active tuned mass damper (ATMD). The purpose of the active control is broadening the vibration attenuation envelope of a primary mass to a higher frequency region identifie...
