TRAPEZ SACLARIN TİTREŞİM DAVRANIŞLARININ SONLU ELEMANLAR VE DENEYSEL MODAL ANALİZLERİYLE İNCELENMESİ

Abstract

Nowadays, trapezoidal sheets, which are mostly used in the manufacture of prefabricated buildings, roofs, containers, sheds and warehouses, may meet structural strength requirements with difference in sizes and thicknesses. When a machine such as a genset is placed inside a container, dynamic loads arise and the standard trapezoidal profiles become insufficient. The dynamic behavior of the structure should also be examined in such products wherefore low vibration and noise values are desired in marketplace. In this study, comparative studies have been carried out with different trapezoidal sheet sections in order to obtain the desired dynamic behavior. Finite element analyzes have been done for different trapezoidal section geometries and the verification study was carried out by performing an experimental modal analysis on a sample in order to match up with the numerical results.
