摘　　要：回转平台是液压挖掘机重要的组成部分,包括工作装置在内的一系列上车部件几乎全部安装在回转平台上。超大型液压挖掘机结构及工艺复杂,承力较大,且造价昂贵,修复难度大,在设计过程中需重点保障其部件的强度和寿命。对某超大型液压挖掘机回转平台在3种典型工况、2种挖掘模式下进行有限元分析,并根据分析结果指导实际生产。Revolving frame is an important part of the hydraulic excavator,on which,a series of on-board components including the equipment are almost installed.Due to its complex structure and process,high bearing capacity,high costs and difficulty in repair,the design process of the super-large hydraulic excavator shall focus on guaranteeing the strength and life of its components.The finite element analysis of the revolving frame of a super-large hydraulic excavator in three typical working conditions and two excavation modes is carried out,and the actual production is guided based on the analysis results.
