摘　　要：论述了机械优化设计中的传统优化设计算法,同时介绍了一种现代的优化设计方法——竞选算法的原理及其求解步骤.采用传统优化设计算法与竞选算法分别对箱形盖板和两杆桁架结构的优化设计问题进行求解,比较了两者间求解方式上的特点,并就竞选算法与传统优化算法间求解效果进行了比较.结果表明,竞选算法是一种非常有效的机械优化设计方法.The traditional optimized algorithms in machine optimization design are demonstrated.A modern optimized design method-election-survey algorithm is introduced with its theory and characteristics.The results of applying the traditional and the election-survey algorithms are obtained,based on the optimum design of the box-shaped cover board and a two-bar truss structure.And then the optimal solutions and the characteristics of the two algorithms are compared.The results show that the election-survey algorithm is an effective method for mechanic optimum design.
