| 摘 要： | 介绍了研究开发的大型结构优化设计系统3SOD的主要功能和特点。3SOD的优化分析系统采用作者提出的启发式分解算法,算法根据约束类型将原优化问题分解成两个子问题,借鉴满性能设计思想和利用结构单元的方向相对差商信息,引入自适应参数和相关求解策略,求解局域约束和全域约束下的两个优化子问题,从而获得原优化问题的优化解。3SOD具有良好的前后处理功能,对于大型结构的优化设计,该系统可获得良好的优化结果。

| Abstract: | The main function and characteristic of optimum design system 3SOD for large-scale structure are presented.3SOD contains the heuristic decomposition algorithm with some heuristic parameters and strategies,which is developed by the author.According to the type of constraints,the algorithm decomposes original optimization problem into two sub-problems.Using the idea of full performance design and the directional relative difference quotient,these two sub-problems are solved and the optimum solution of the original problem is obtained.3SOD has powerful pre-and postprocessor.It can obtain a good solution for the optimum design of large-scale structure. |
