 将人工智能搜索策略应用于抗疲劳优化设计中,针对工程实际中大量存在的离散变量的优化问题,提出了一套不同于传统数学规划法的方法,从根本上解决了处理离散变量的困难。还以多钉多层板接头为算例,作了优化计算,说明本文提出的方法可行,计算程序适用。并且优化结果比数学规划法好。

ANTI-FATIGUE OPTIMIZATION DESIGN BY ARTIFICIAL INTELLIGENCE STRATEGY

The artificial intelligence strategy is applied to the optimum anti-fatigue design of structural details. A set of approaches quite different from the traditional mathematical programming method is put forward. By setting up a state space of discrete design variables, to, which the intelligence search strategy is applied, the integralization of discrete variables can be avoided. A lot of practical experience of the experts has been collected in making the search strategy so as to make the search process simple, fast and the results of the optimum design reliable. An example of optimum anti-fatigue design for a typical structure detail of aircraft is worked out using the present method. Comparison between the results obtained by this method and that by the mathematical programming m ethod shows that the present method is better. Verification experiments conducted bv the author show that the method proposed is feasible and reliable.
