Abstract: Portal axles (or portal gear) are an offroad technology where the axle tube is above the center of the wheel hub and where there is a reduction gearbox in the hub. It is the shaft which must tough and strong, since composite materials have promising properties, which can reduce the weight and almost equal to conventional material properties. In this paper portal axle shaft analyzed by Finite Element Analysis considering three different composite materials and varying parameters. i.e rib thickness and hollow shaft thickness are consider. Some of the parameters are kept constant they are depth of spokes, rib fillet radius, number of spokes. Torsional strength of the shaft compared for three different materials. When Rib Thickness are varied Deformation and Stresses are almost same for Kelvar/Epoxy and Boron/Epoxy materials but varied for E Glass/Polyester Resin. Similarly When Shaft Thickness is varied the results are same for Kelvar/Epoxy and Boron/Epoxy but varied for E Glass/Polyester Resin material.
