    摘要: A pneumatic tire having a tread reinforcement layer constituted by a steel cord strip layer adjacent the carcass and an aromatic polyamide cord strip layer superposed to the steel cord strip layer in a parallel side-by-side relationship. The aromatic polyamide cord strip layer is folded at its both edges toward the center, in such a manner that the folded portions contact the main portion in a parallel side-by-side relationship. The main portion has a width ranging between 100 and 110% of the width of the tread surface, while the width of each folded portion ranges between 27.5 and 35% of the width of main portion. Furthermore, the free edge of each folded portion is located at a distance from the center of the outermost circumferential groove in the tread surface, which distance being between 25 and 75% of the distance between the outermost groove and the adjacent groove.

    摘要: The overall material constant of a composite material is computed where the composite material includes multiple kinds of material components in a matrix phase, each of the material constants of the material components and the matrix phase being known. First, for the composite material, an equation, having the material constant of a virtual composite material as an unknown, is prepared by defining the virtual composite material in which each of the material components is dispersed in a form of spherical particles in the matrix phase at a known volume fractions. Next, the overall material constant of the virtual composite material is found as the overall material constant of the composite material by solving the equation. In this case, the equation is a recursive equation which is obtained using the self-consistent method. The volume fraction of a material component in the composite material is computed using the equation.

    摘要: Values of multiple tire dynamic element parameters are set for a tire dynamic model constructed using the tire dynamic element parameters for calculating a tire axial force and a self-aligning torque under a given slip ratio. Next, the values of the tire axial force and the self-aligning torque are calculated using the tire dynamic model and output. The tire dynamic model allows a center position of a contact patch thereof against a road surface to move in accordance with a longitudinal force that occurs as the tire axial force when a slip ratio in a braking/driving direction is given so that a position of the contact patch moves in a longitudinal direction due to the longitudinal force. When designing a vehicle or when designing a tire, the tire dynamic model is used.
