以各杆件的截面积为设计变量、结构总重量为目标函数、在衍架体系中使用较广泛的优化方法——齿行法是传统的满应力设计方法的改进。它考虑到结构优化过程中目标函数值的变化,保证了结果的可行性,是一种易被工程技术人员接受的优化设计方法。采用齿行法进行结构优化设计同采用其它优优化策略一样,可以取得比传统设计为好的经济效果,在消耗相同数量材料的前提下则
Taking the cross-sectional area of each member as the design variable, the total weight of the structure as the objective function, and the more extensive optimization method used in the truss system, the tooth row method is a modification of the traditional full-stress design method. It takes into account the changes in the value of the objective function in the process of structural optimization and ensures the feasibility of the results. It is an optimization design method that is easily accepted by engineering technicians. The structural optimization design using the tooth row method is the same as using other optimal optimization strategies. It can achieve better economic results than the traditional design, under the premise of consuming the same amount of materials.
