Provided is a figuration method of tire cross section, comprising: excellent target performance of setting a tire; setting the variable used for confirming the ground pressure into a design variable and utilizing the cross section shape for optimizing the process, thus to get a tire cross section having optimized ground pressure; and setting the variables for confirming the rigidity, tension, and stress into the design variables and utilizing the cross section shape to optimize the process, thus to obtain the optimized rigidity, tension, and stress. The cross section shape optimizing process comprises the steps of: inputting basic information, design variables, and objective function according to the objective performance of the tire; generating the first shape of the tire cross section via the cross section shape automatic design process based on the basic information, design variables, and objective function; generating the second shape of the tire cross section via the cross section shape automatic gridding process according to the first shape; and comparing the finite-element analysis end value of the second shape to the objective performance, and changing the design variables of the step one to start from step two again if the conditions are not satisfied, and if the conditions are met, the optimum tire cross section is obtained and the process is over. |
