    摘要: A pneumatic tire has two belt layers, each having a plurality of strip pieces formed by pulling together and rubberizing a plurality of steel cords. Strip piece width, strip piece thickness, belt layer cord angle with respect to a tire circumferential direction, numbers of the strip pieces of inner and outer belt layers, and circumferential lengths of the inner and outer belt layers are respectively denoted by A, G, θ, N1, N2, L1 and L2. N2 is equal to N1, and N1 is an integer satisfying L1=N1×A/sin θ. The inner belt layer is formed by joining the N1 strip pieces so each side of each strip piece is butted with one side of another strip piece. The outer belt layer is formed by aligning the N2 strip pieces on the inner belt layer in the tire circumferential direction with spaces of width 2πG/N2 disposed between adjacent strip pieces.

    摘要: Disclosed is a method of designing rubber composite executed as follows. A shape of the rubber composite, a shape of the each part (i) constituting the rubber composite and physical properties of a rubber material used for each part (i) are tentatively selected respectively. Thereafter, the rubber composite is divided into many finite elements, and strain in each element is calculated by the finite element method to obtain maximum principal strain (εi)max of the elements in each part (i). Then, the tentative selections of the shape of the rubber composite, the shape of each part (i) and the physical properties of the rubber material, and the calculations by the finite element method are repeated until an allowance ratio Sia calculated as a ratio of strain (εi)b at break to the maximum strain (εi)max becomes equal to a specified reference allowance ratio S0 or higher in all of the parts (i). The shape of the rubber composite, the shape of each part (i) and the physical properties of the rubber material are thus determined.
