Optimize the Structure Parameters of Tread Pattern Based on the Fuzzy Genetic Arithmetic

In order to optimize the structure parameters of tread pattern and improve the efficiency of Noise-Reduction, The width and length of pattern block, the width length and direction of pattern slot, the number of pattern strip the basic number of pattern pitch, the pitch array and the pattern misplacement were investigated as the structure parameters of tread pattern sound generating mechanism. Thereby the principle and method of tire noise-reduction were educed. The fuzzy genetic arithmetic was proposed based on the analytic result of pattern parameters, the fuzzy theory and the genetic principle, which may optimize the structure parameters of tread pattern. The method of fuzzy noise tread patterns, and the use of genetic arithmetic to optimize the structural parameters to achieve the purpose of reducing tire noise, and a low-noise tread patterns structure was proposed at the same time. The research was successfully applied to the design of way for the low-noise tread patterns.
