摘　　要：继电器产品的优化设计是在给定的负载条件或环境条件下,在对继电器产品的性态、几何尺寸关系或其他因素限制约束范围内,确定设计参数、目标函数、约束条件以形成优化设计模型,并选择恰当的优化方法以获得最佳设计方案的一系列工作。继电器的体积数学模型涉及到机、电、磁、热等方面,其目标函数和约束函数均是高度非线性的。传统演化算法求解问题时容易陷入局部极小值。在简单演化算法的基础上,结合正交实验法的基本思想,将其应用于演化算法的种群初始化、交叉算子,并引入自适应正交局部搜索来防止局部收敛,得到了一种新型的正交演化算法。通过一系列数值实验验证了该算法的高效性。Optimal design of relay products determine the design parameters in the given load conditions or environmental conditions,the state of relay products,geometry or other factors within the scope of restrictions,and makes sure of the design parameters,object function,constraints in order to form an optimized design model,and selects the appropriate optimization method to obtain the best design of a series of works.Mathematical model of the relay volume involves in mechanical,electrical,magnetic,thermal,etc.,the objective function and constraints are highly nonlinear function.Traditional evolutionary algorithm is trapped into the local minimum easily.Therefore,based on a simple evolutionary algorithm and combining the base ideology of orthogonal test,applied it to the population initialization,crossover operator,as well as the introduction of adaptive orthogonal local search to prevent local convergence,a new orthogonal evolutionary algorithm is proposed.The series of numerical experiments have proved the efficiency of this algorithm.
