Analysis of the Effects of Back-stayed Arrangement on the Mechanical Properties of Corbel Shelf

With AS/RS corbel shelf as research object, the orthogonal experiment was designed, which is composed of 21 groups of schemes and 3 kinds of load conditions. By using the Rack Computer-Aided FEA System based on SAP84, this paper presents the effects of grounding back-stayed and the ground floor height of back-stayed on the strength, rigidity and stability of corbel shelf under normal load, horizontal load in X direction and horizontal load in Y direction. The results show that in all conditions, grounding back-stayed improves the strength and stability of column, and the strength and stability of corbel shelf will be enhanced with the decrease of the ground floor height of back-stayed. This research provides a theoretical basis for the analysis and design of corbel shelf.
