根据某型车载钻机相关技术要求,采用伸缩桅杆结构形式,分析了桅杆各关键结构及其工作状态。模拟桅杆实际工况,确定实际受载情况并进行相应的边界条件处理,运用有限元法分析了桅杆关键结构件-支撑架与滑动架的应力分布和位移变形情况,为该型车载钻机的后续设计研究提供了理论依据,对同类型桅杆的分析研究具有一定的借鉴应用价值。 According to the technical requirements of a certain type of vehicle rig, the telescoping mast structure is used to analyze the key structure of the mast and its working status. Simulation of mast actual conditions, to determine the actual load situation and the corresponding boundary conditions, using finite element analysis of the mast of the key components - the support frame and the carriage of the stress distribution and displacement of the deformation for the type of car rig follow-up Design provides a theoretical basis for the analysis of the same type of mast has some reference value.
