Abstract
A design method for an outer contour structure of a tire capable of reducing tire wind resistance, including the following steps: step 1, establishing an initial tire model; step 2, building an tire aerodynamic drag calculation model; step 3, designing a testing scheme using tire five contour parameters; step 4, building a function relationship between tire five outer contour parameters and an aerodynamic drag coefficient values, and verifying the accuracy of the function relationship; and step 5, obtaining tire five outer contour parameters when the aerodynamic drag coefficient value is smallest by using an optimization algorithm. The design method effectively avoids the blindness problem in the design process of the tire outer contour structure and can effectively reduce the design cycle number of the tire outer contour structure, thereby improving the improvement efficiency, meanwhile, it is benefit to reduce tire aerodynamic drag and improve vehicle economy and reduce harmful emissions.
