APPLICATION OF GENETIC ALGORITHM TO MULTIOBJECTIVE OPTIMIZATION OF TIRE STRUCTURE

  • A genetic algorithm(Pareto GA), based on a sharing niche technique, is applied to search a Pareto optimal set in a multiobjective optimization problem. On the basis of considering synthetically the belt durability and tire weight, a mathematical model was founded by a three-dimensional finite element analysis and indoor durability test. The mathematical model was calculated by means of Pareto GA, and the Pareto optimal set, which was dispersed well, was attained. In order to evaluate the result of optimization, the tire with the optimized belt structure was analyzed by the three-dimensional finite element analysis technology, and the analysis result was compared with that of the original tire. The result shows that the goal of optimization is achieved.
