摘要
针对桁架形状优化问题,提出了一种改进的模拟退火算法．在该算法中提高了计算精度、计算效率和通用性;针对桁架形状优化设计,采用多目标规划的思想,将离散变量优化和连续变量优化结合起来．数值算例验证了改进模拟退火算法的可行性和有效性．
For the global shape optimization of truss structures, an improved simulated annealing is proposed, which enhances the accuracy, efficiency and versatility. The optimizations of continuous variables and discrete variables are combined by using the method of multi-objectives. And the results show that the algorithm enjoys high precision.
