摘　　要：主梁是大型压力机的关键受力构件之一,其最优设计问题是一类很难求解的非线性规划问题。传统的优化方法在解决这类复杂优化问题时显示出自身的一些不足。针对传统优化算法的局限性,提出用简单实用的基于父子混合选择遗传算法,对大型压力机的主梁进行优化设计。并用一个仿真算例验证了该算法的有效性和可行性。Main gilder is one of the most important forced parts of large pressing machine. Its optimal design is a ＂hard＂ nonlinear optimization problem. Classical optimization algorithms are generally not successful in solving such hard optimization problems. Aiming at the limitations of traditional optimization design, puts forward a father-offspring combined selection genetic algorithm to solve this optimization problem effectively. A numerical example is used to demonstrate the validity and availability of the proposed algorithm. Optimization results show that the father-offspring combined selection genetic algorithm is effective.
