Tread pattern pitch design method and device

Abstract

The invention discloses a tread pattern pitch design method which comprises the following steps: inputting tire perimeter and pattern pitch information; calculating the length and number of each pitch based on an average energy distribution principle according to the input tire perimeter and pattern pitch information; generating a preliminary pitch arrangement mode according to the calculated length and number of each pitch; and evaluating the preliminary pitch arrangement mode based on the average energy distribution principle, and generating a final pitch arrangement mode by changing the pitch arrangement through an evolutionary algorithm. According to the method in the embodiment of the invention, the length and number of each pitch are calculated based on the average energy distribution principle according to the tire perimeter and pattern pitch information so as to generate the preliminary pitch arrangement mode, the preliminary pitch arrangement mode is evaluated, the final pitch arrangement mode is generated by changing the pitch arrangement through the evolutionary algorithm, the cost is low, the efficiency is high, and the tread pattern pitch can be scientifically designed. The invention also discloses a device for designing the tread pattern pitch.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a tire tread pitch design method and device. Background technique [0002] The usual tire pattern design is carried out by engineers with many years of pattern design experience. According to their own experience, they design tire patterns with good noise performance, thereby reducing tire noise. But before the pattern design, the most important thing is the tire pattern pitch parameter design and pitch arrangement design. The usual design methods rely on experience and have no scientific basis, which makes it very difficult to further improve. [0003] In related technologies, such as pattern pitch arrangement design, by satisfying the principle of constant tire circumference, a certain number of initial populations are randomly generated, and then the fitness calculation is performed for each pitch arrangement mode. If the convergence requirements are met, the output Result; ...
