摘要
根据牙轮钻机钻架的结构特点，提出分组结构优化设计方法，编制了基于准则法的分组结构优化程序．以ＹＺ５５牙轮钻机为例进行了钻架结构优化设计，给出两种优化方案下的病应力最优解．
This paper presents a group optimum method for the structural design of tower of three-cone blasthole rigs according to their structural characteristics,and makes a group structural optimization program based on optimality criterion method. Taking YZ55 three-cone blasthole rigs as example,carries out the structural optimum design of its tower,and gives out the results of optimization under two plans.
