Abstract: The paper deals with the optimum design of mast sturcture with givenpti structural arrangemant. The objective is to minimize economic quota of the mast structure. The stress, displacement, member size, local buckling and system buckling constraints of the structure are taken into account. All practical loads on the mast structure such as the wind load, the dead load and the hook load are considered. Two existing mast structures are computed with the planned program and compared with the orignal design.

摘要： 本文以井架结构经济指标为目标函数,对给定结构几何拓扑布局的陆地用石油钻井井架进行优化设计,使井架在多种约束及工况下结构经济指标最佳。设计变量是井架构件截面尺寸。约束有应力、变位、杆件局部稳定、刚度及结构系统稳定。文中考虑井架实际受载情况:自重、风载、立根载荷、大钩静负荷以及各种恒载。文后根据所编制的程序计算了两个工程实际井架,并与原设计方案进行了比较。
