摘　　要：变幅机构是旋挖钻机的重要组成部分,而大臂是变幅机构的主要构件。在变幅、钻进和提钻等工况下,变幅机构是旋挖钻机主要的受力机构,其中大臂承受了各种载荷。本文分别对各种工况进行分析,选取旋挖钻机最不利的姿势作业且承受最大载荷时大臂的结构强度进行分析,为大臂的结构设计、优化及拓扑优化设计等提供理论依据和技术基础。Luffing mechanism is an important part of rotary drilling rig. Boom is the main component of luffing mechanism. Rotary drilling rig in the luffing, drilling and jacking and other conditions, the luffing mechanism is the main force agencies, the arm to bear a variety of loads, the paper were on a variety of conditions were analyzed, This paper analyzes the structural strength of the boom when the most unfavorable posture of the rotary drilling rig is under maximum load and provides the theoretical basis and technical foundation for the structural design, optimization and topological optimization design of the boom.
