Title:
DESIGN METHOD FOR A PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/1994/016877
Kind Code:
A1
Abstract:
A design method for a pneumatic tire according to the present invention comprising the steps of determining a tire basic model representing tire cross-sectional configurations including the internal construction and divided into a plurality of elements, an objective function representing a physical value for evaluating a tire performance, a design variable for determining the cross-sectional configurations of the tire, and limiting conditions for limiting the cross-sectional configurations of the tire, obtaining a corrected model of the tire in which the design variable is changed by a unit amount DELTAr1, calculating values of the objective function and limiting conditions of the corrected model, calculating sensitivity for every design variable and calculating an estimated value of a changed amount of the design variable that maximizes the value of the objective function by using sensitivity so calculated while allowing for the limiting conditions, repeating the above steps until the values of the objective function converge, and determining the configuration of a tire based on the design variable when the values of the objective function converge upon the estimated value.
