机械工程全局优化设计的遗传算法

A Genetic Algorithm for Global Optimization Design of Mechanical Engineering

针对机械工程设计中经常遇到的多个局部极值的参数优化设计问题，探索了应用遗传算法求解其全局最优解的途径。文中讨论了遗传算法的基本构造模型，提出了新的适合度技术、新的交叉算子、新的变异算子和算法终止准则。最后，给出了遗传算法在机械工程优化中应用的两个实际算例。

Taking aim at the phenomena of multiple local extreme values which generally exist in the optimization design of mechnical engineering, a genetic algorithm is introduced to search the global optimal solution. The basic strategy of the genetic algorthm is discussed. The new fitness techniques, the new crossover operator, the new mutation operator and the stopping rules are proposed. Two practical examples in mechanical engineering design are described.
