Abstract:

The emphases of stacking sequence of composite laminate focus on optimization method study without considering stacking sequence design heuristics.Optimization model based on design heuristics and adaptive genetic algorithm is presented and the rules of design heuristics are expressed by fuzzy IFTHEN with believe ratio.A fitness function of adaptive genetic algorithm is established by using TsaiHill rule.Rules of design heuristics are used as heuristic constraints in laminate stacking sequence optimization model.The optimization results show the superiority and practicability of the model comparing with the results calculated using adaptive genetic algorithm without rules of design heuristics.
Key words: composite material; design heuristics; stacking sequence;adaptive genetic.
