摘要
以WY100C液压挖掘机(斗容量为1 m3)为样机,对挖掘机反铲工作装置——铲斗应用Pro/E建立实体模型,并应用Pro/MECHANICA模块对挖掘机铲斗的设计模型在受最大应力的危险工况下进行有限元强度分析。分析结果表明,挖掘机铲斗的前部斗齿、斗后壁耳板的根部、铰接处和补强区域是最危险的部分,设计时应重点考虑其强度要求,其它部分相对较安全。挖掘机反铲工作装置-铲斗的强度分析为铲斗的设计及改善铲斗的性能提供了理论依据。
Taking WY100C hydraulic excavator （bucket capacity for 1 m^3） as a prototype, a physical model of the excavator backhoe working device （bucket） was established by Pro/E. The finite element intensity analysis of the design model of the bucket was made under the circumstance of dangerous working condition of the largest stress through Pro/MECHANICA module. The results indicate that the bucket teeth in the front of the bucket, the roots of the bucket back lug, the hinge areas and the reinforcement areas are the most dangerous parts. Designers should especially take intensity requests of these locations into account. Other parts are relatively safe. The intensity analysis of the excavator backhoe working device （bucket） provides a theoretical basis not only for bucket design, but also for improving the performance of bucket,
