摘　　要：为了提高优化效率,采用先验法、字节型动态编码方法以及自适应变异技术对遗传算法进行了改进,并将其与有限元分析计算相结合,提出了一种适用于复杂结构模型的优化分析方法。利用该优化方法对某型重机枪枪架结构参数进行了优化,仿真结果表明,本文提出的优化方法是可行的,优化效果良好。The genetic algorithm method was modified by a prior method, a dynamic byte coding method and a self-adaptation variation technique in order to improve its optimization efficiency, a new optimization method combined with the finite element and improved genetic algorithm was brought forward which is suitable for complex structural model. The mount structural parameters of a heavy machine gun were optimized by the optimization method. The simulated results show that the method is feasible and efficient.
