摘　　要：挖掘机是土石方工程的主要施工机械,由于其作业对象、载荷、操作等的不确定性,挖掘机工作装置的受力情况较为复杂。液压挖掘机的工作装置主要由铲斗、斗杆和动臂构成,基于不同优化部位、不同优化目标和不同优化算法,其优化设计具有多样性和复杂性。详细介绍了关于液压挖掘机工作装置的优化方法,分别就局部与整体优化、新型结构设计与应用和现代优化架构三方面进行展开,总结了液压挖掘机工作装置的优化方式和未来发展趋势,为液压挖掘机工作装置的优化设计提供参考。Excavators are the main construction machinery for earth and stone engine. Due to the uncertainties of the work object, load, and operation, the force of the working device of the excavators becomes more complicated. The working device is mainly composed of bucket, arm and boom. Based on different optimization parts, optimization objectives and optimization algorithms, the optimization design of excavators working device has diversity and complexity. An optimization method of working device of hydraulic excavator is introduced in detail, respectively from three aspects of local and overall optimization, new structure application of simulation and modern optimization algorithm. The optimization methods and future development trend of hydraulic excavator working device are summarized, which provides a reference for optimal design of hydraulic excavator working device.
