Design and Static Structural Analysis of Aircraft Floor Beam

Floor beam is a structural element of fuselage which is mainly used for providing horizontal space to aircraft crew and is fixed with fuselage skin. In this I-section beam is picked for designing the fuselage floor beam which is better in comparison to other cross sections. In this, the design of aircraft floor beam is conceptual design for the enhancement of strength, durability, cost and weight reduction. The major problems of existing aluminium floor beam are increased weight and less stiffness. Hence, CFRP (carbon fibre reinforced plastics) has chosen for the designing of floor beam in the aircraft. After the selection of material and cross section of floor beam, the whole parameters of cross section of floor has studied and designed in UG NX8 software with the standard dimensions of a floor beam then the model is imported to Ansys 14.5 for the analysis and optimization. The expected outcome is to reduce the weight to strength ratio, cost, design and style outlook with weight reduction of fuselage. Citation: Santosh Yadav.
