英文摘要：

Based on the genetic algorithm,the adaptive concept was introduced to propose an adaptive genetic algorithm,by which the structural parameters of tread patterns were optimized.The defects,such as premature convergence and inefficient search,were eliminated by using adaptive genetic algorithm.At the same time,the speed and efficiency of optimization increased,and the convergence algebra was reduced.The stability of software was also improved.
