THERMAL DEFORMATION ANALYSIS OF THE U-SHAPED THIN SHELL STRUCTURES WITH STIFFENERS BASED ON ABAQUS

Abstract

Abstract: The U-shaped thin shell structures with stiffeners are widely used in the field of aeronautic and aerospace. However, due to the thermal deformation of the cross section of the structures, the hole-position and drilling are carried out by the special production tools or separate measurement, which lead to the complex procedure and long manufacture cycle. In this study, the finite element analysis of ABAQUS was employed to calculate and predict the sectional dimension of the U-shaped thin shell structure. The results show that the predictive values in the design condition of local modeling with steel tool were consistence with that of the actual products. While the calculating results of the integrated modeling were smaller than that of actual dimension, which could be attributed to the consideration without steel tools in this modeling. It is concluded that the ABAQUS can be used for the thermal analysis and prediction of the U-shaped thin shell structure with stiffeners.

Key words: ABAQUS software, thin shell structure with stiffeners, thermal deformation
