The invention discloses a method for designing tire pattern pitch, comprising the following steps: inputting tire circumference and pattern pitch information; calculating each pitch based on the principle of average energy distribution according to the input tire circumference and pattern pitch information According to the calculated length and number of each pitch, a preliminary pitch arrangement is generated; based on the principle of average energy distribution, the preliminary pitch arrangement is evaluated to change the pitch arrangement through an evolutionary algorithm to generate the final pitch Arrangement. The method of the embodiment of the present invention generates a preliminary pitch arrangement by calculating the length and number of each pitch based on the principle of average energy distribution according to the tire circumference and pattern pitch information, and performing evaluation to change the pitch through an evolutionary algorithm The arrangement generates the final pitch arrangement, which has low cost and high efficiency, and can scientifically design the pitch of the tire pattern. The invention also discloses a design device of tire 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; ...
