Farklı Standartlara Göre Silo Cidarı Üzerindeki Gerilme Değişimlerinin ANSYS ile İncelenmesi

Abstract

In this study, the optimal dimensions of the silo were investigated for barrel-type cylinder, conical outlet, steel construction silo which used in Tombul hazelnut storage in the Giresun province conditions. 10, 11, 12, 13, 14, 15 ve 20 mm wall thickness for 1635 tons storage capacity silo were examined in the study. For this purpose, pressure loads acting on the silo wall surface (vertical, horizontal, friction traction pressure load) using Eurocode 1 and Australian standards were calculated for different wall thicknesses at filling and discharge conditions. This calculated pressure loads by entering in ANSYS finite element software program, stresses which occurring in different directions on the surface of wall was determined. In the study, it was determined that 10, 11 and 12 mm wall thickness were not reliable in terms of stresses caused vertical pressure load in the filling conditions. The optimum silo dimensions will not lead to any structural problem are emerging as the silo which has 13 mm wall thickness when considering storage capacity and the maximum von Mises stresses. This silo with barrel-type cylinder and conical outlet shows the most appropriate features in terms of engineering in Tombul hazelnut storage. At the result of the analysis according to Australian standard (AS 3774) of proposed this type of silo was observed to be reliable (in terms of pressure loads acting on the surface of the silo wall).
