INFLUENCE OF CONTACT SHAPE OF TRUCK TIRES ON PLATE-BENDING STRESSES IN ALUMINUM DECKS

Abstract

In this study, a truck tire loading device is produced and, with this, the influence of the contact shape of a truck tire on the plate-bending stresses in aluminum decks is clarified. First, the characteristics of the contact shape and pressure of a tire are revealed and the relations of load are formulated with the contact area, the average contact pressure and the contact radius of a tire. Next, the investigation on the plate-bending stresses occurring in an aluminum deck shows that the relation between load and the plate-bending stresses is nonlinear. Last, the comparison of the plate-bending stresses produced by truck-tire loading and rectangle-area loading discloses that the plate-bending stress created by rectangle-area loading is not on the safe side.
