Dynamic Behavior of the Inertial Platform Related to the Research Facility Building Laser and Gamma at ELI-NP Bucharest

This paper aims to study the vibration of large inertial platform from Laser + Gamma building that is part ELI-NP project. In order ensure a precisely positioned radiation beam, it necessary shocks and vibrations coming external environment are damped or absorbed until they reach work installations. ensured by on which devices positioned, supported spring batteries shock absorbers. A rigid body model developed in this regard comparison with finite element concrete conducted. It has been found low modes can be obtained help model, also advantage simplicity very little time required obtain results.
