| 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.

| Abstract: | Main grider 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. |
