| Abstract: |
| The aim of this work was to design the structure of the main force-bearing parts for intermediate bulk container frame, namely the floor and beam of the frame. Firstly, the basic models of the reasonable and reliable floor and beam were designed according to the service conditions and the environment. Secondly, the influences of rib number, the section height and the radius of the middle rib on the support of beam were studied, and four kinds of beam structures were designed. Finally, the best structure was selected based on the finite element analysis of several structures with different shapes and dimensions. It was found that the structure with smallest stress and deformation was the one using rib grain for the floor, with a rib number of five, a beam section height of 16.5 mm and a middle rib radius of 47 mm. The loading requirements could be met, and the service life of the frame could be extended through the design and analysis of the floor and beam. |
