中文摘要:
      以层合板结构的临界屈曲载荷系数最大化为优化目标,基于改进型模拟退火算法对层合板结构铺设角度和铺层顺序进行优化。由于层合板结构的铺层角度是离散变量,模拟退火算法适合求解离散变量的优化问题。利用模拟退火算法优化层合板铺层,在算法内采用并行计算、引入记忆功能同时设置双阈值终止准则,有效地提高了优化过程的收敛速度,同时避免优化过程中出现局部最优解。以临界屈曲载荷系数作为目标函数,选取复合材料层合板的铺设角度顺序为设计变量,采用改进的模拟退火算法得出复合材料层合板的最优铺设角度以及铺层顺序。
英文摘要:
      In order to maximize the critical buckling load coefficient, the ply stacking sequence and ply laying angle of laminated composite plate are optimized with improved simulated annealing algorithm in this paper. By using parallel computation and setting up double threshold the local optimal solution appeared in the process of optimization is avoided and meantime the rate of convergence is accelerated. Fiber laying angles and stacking sequence of composite laminates plate are chosen as design variables, and the design objective function is the critical compressive load. Comparative analyses show that the optimal ply stacking sequence and ply laying angle of laminated composite plate can be obtained with improved simulated annealing algorithm.
