摘　　要：吊卡作为钻井提升系统的重要结构,强度与可靠性要求极高。为提高吊卡的强度与安全可靠性,对吊卡吊臂部位进行结构优化。利用有限元软件ANSYS workbench对吊卡的静态特性进行了研究分析;在此分析基础上,对吊臂结构优化设计参数进行了灵敏度分析与实验设计;并基于响应面法建立了优化的数学模型,再通过遗传算法得到最优设计方案。结果表明:当吊臂截面厚度b为94mm,吊臂截面半径R为87mm,吊臂截面偏离角度β为37°时,吊臂的最大应力值降低12.5%,并通过试验进行了验证。提高了吊卡的强度与安全储备,为吊卡结构改进设计提供了理论指导。As an important structure of drilling hoist system,the requirement of the drill pipe elevator strength and reliability are very high.In order to improve the strength and safety reliability of the crane,the structure of the drill pipe elevator was optimized.The static characteristics of the drill pipe elevator are studied and analyzed by using ANSYS Workbench;On the basis of this analysis,the sensitivity analysis and experimental design of the optimal design parameters of the drill pipe elevator are carried out;and an optimized mathematical model is established based on the response surface method,and then the optimal design scheme was obtained by genetic algorithm.The results show that when the drill pipe elevator section thickness b is 94mm,the boom section radius R is 87mm,and section deviation Angleβis 37°,the maximum stress value of the drill pipe elevator decreases by 12.5%,and it is verified by experiments.It improves the strength and safety reserve of the crane,and provides theoretical guidance for the improvement design of the drill pipe elevator structure.
