A niche genetic algorithm for the design of mechanical optimization

针对在机械设计中经常遇到的多个变量、多个局部极值的参数优化设计问题,提出了应用小生境遗传算法求解多峰值函数全局最优化解的途径。对小生境遗传算法的基本构造模型和实现技术给出了全面的描述。最后,以曲柄摇杆机构的优化设计为算例,验证了该算法的有效性。

Taking aim at the problem of multi-variable and multiple local extreme values which generally exist in the optimization design of mechanical engineering, a niche genetic algorithm is introduced to search the global optimal solution in this paper. The basic strategy and achieve technology of niche genetic algorithm are accounted completely in this paper. At the end of this paper, an example of the niche genetic algorithm applied in the optimal design of crank-shake pole mechanism is described, and this example illustrates that the niche genetic algorithm is effective.
