摘　　要：针对机载锚杆钻机钻臂质量过大会影响机动性和工作稳定性等问题,以JMZ型机载锚杆钻机钻臂为研究对象,采用响应面法进行结构优化。以钻臂的尺寸参数为设计变量,强度和刚度为约束条件,质量为优化目标,采用中心组合设计法,建立响应面模型,分析各变量对钻臂最大等效应力、最大变形和质量的影响规律,运用多岛遗传算法对响应面模型进行寻优求解,得到最优参数组合。结果表明:固定臂内筒截面尺寸对钻臂最大等效应力的影响最大,伸缩臂内筒截面尺寸对钻臂最大变形和质量的影响最大;优化后钻臂强度和刚度均满足要求,钻臂质量下降了7.83%,最大等效应力下降了14.58%,达到了优化目的。To address the challenges of reduced mobility and operational stability caused by excessive boom mass in onboard roof bolters,this study focuses on the structural optimization of a JMZ-type drill boom through response surface methodology.With the size parameter of the drill arm as the design variable,strength and stiffness as the constraint condition,and mass as the optimization objective,the response surface model was established using the central combination design method,and the influence law of each variable on the maximum equivalent stress,maximum deformation and mass of the drill arm was analyzed.The response surface model was optimized and solved by using the multi-island genetic algorithm,and the optimal parameter combination was obtained.The results show that the cross section size of the inner cylinder of the fixed arm has the greatest influence on the maximum equivalent stress of the drilling arm,and the cross section size of the inner cylinder of the telescopic arm has the greatest influence on the maximum deformation and quality of the drilling arm.After optimization,the strength and stiffness of the drilling arm meet the requirements,the mass of the drilling arm is reduced by 7.83%,and the maximum equivalent stress is reduced by 14.58%.
