ASPECTS ON THE DYNAMIC ISOLATION FOR BUILDINGS USING PENDULUM SYSTEMS

Aurora POTÎRNICHE

Abstract


This paper briefly presents an analytical research regarding to the complex influences of passive elastic elements about changing dynamic characteristics of the vibration absorbers using pendulum devices.  In the paper is developed a system model which contains a base subsystem that must be isolated and an additional subsystem of a dynamic restricted pendulum absorber type. The studied case considers elastic elements and disregard damping elements. The author has proposed a set of interest parameters and for these parameters variation it was made an analyze of those behaviour on the overall system.

Keywords: pendulum device, vibration isolation, dynamic restricted pendulum absorber.
