    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.

    摘要: In a prediction of abrasion characteristic of a tire, a characteristic curve of a tire axis force generated on a tire rotation axis at the slip ratio applied to the tire and changed depending upon the slip ratio is acquired. From the characteristic curve, values of tire dynamic element parameters determining the characteristic curve are derived based on a tire dynamic model constituted by the tire dynamic element parameters. Furthermore, a tire sliding amount based on a sliding region, the sliding region and an adhesive region formed on the contact patch of the tire at the applied slip ratio are calculated by applying the values of the tire dynamic element parameters to the model. Lastly, an abrasion characteristic of a tread part of the tire at the applied slip ratio is predicted by using the tire sliding amount with abrasion characteristic data of a tread rubber of the tread part. According to the prediction results, a tire is designed and produced.

    摘要: A transient response of a tire is simulated by using a effective data of a physical amount. The physical amount is set as a rolling condition of the tire and varies in time. The effective data of the physical amount is calculated by a convolution integral of a response function of an introduced first-order lag response and a time gradient of time-series data of the physical amount. In a tire model determining method, a time constant of a response function of the first-order lag response is determined from measured transient response data. In a tire transient response data calculating method, a transient response data is calculated by using the effective data of the physical amount which is calculated by using a desired physical amount and the first-order lag response.
