Optimization Research on Wall Thickness of a Double-Wall Steel Insulation Silo with Multiple Bolted Joints

Abstract

This paper introduces a new double-wall fabricated steel insulation silo with multiple bolted joints. The software ANSYS is utilized to model a 1000-ton double-wall fabricated steel insulation silo with multiple bolted joints and calculate its stress and displacement. The silo is optimized by adjusting the wall thickness of the silo. The model which uses the original thickness is defined as Model 1. The optimized model is defined as Model 2. The stress and deformation of these two models were comparatively analyzed. The results show that the maximum stress and the maximum displacement of Model 2 are both smaller than the specified values. Furthermore,it saves about 40.7% with the steel quantity compared with Model 1.
