Abstract

THIS PAPER PRESENTS THE RESULTS OF THE MODAL ANALYSIS OF A SECTOR OF THE TOROIDAL VACUUM VESSEL OF A NEW EXPERIMENTAL MACHINE FOR RESEARCH IN THE FIELD OF CONTROLLED THERMONUCLEAR FUSION (FTU - FRASCATI TOKAMAK UPGRADE). THE VACUUM VESSEL, ONE OF THE MOST CRITICAL COMPONENTS OF THE EXPERIMENTAL DEVICE, CONSISTS OF 12 STAINLESS STEEL TOROIDAL SECTORS, AND IT IS DESIGNED TO WITHSTAND PULSED ELECTROMAGNETIC LOADS DURING OPERATION. RESULTS OF THE MODAL ANALYSIS OF THE STIFFENED TOROIDAL SHELL SECTOR ARE COMPARED AND DISCUSSED WITH REGARD TO THE EXPERIMENTAL DATA. THEORETICAL EIGENVALUES AND EIGENVECTORS HAVE BEEN PREDICTED BY MEANS OF ABAQUS FINITE ELEMENT CODE. EXPERIMENTAL ANALYSIS HAS BEEN CARRIED OUT ON A FULL SCALE MODEL AND NATURAL FREQUENCIES HAVE BEEN MEASURED. SATISFACTORY AGREEMENT BETWEEN EXPERIMENTAL AND THEORETICAL EIGENVALUES HAS BEEN FOUND.
