摘　　要：将振动理论应用到液压挖掘机挖掘作业过程中不仅可以减小挖掘阻力,降低能耗,而且能够提高挖掘机特种作业(如冻土开挖)的能力。该文对振动掘削技术进行介绍,并分析液压挖掘机振动掘削减阻的机理。在此基础上,研究和设计了挖掘机振动掘削液压系统,该系统可以根据作业对象的不同特点,及时调整振动频率和振幅;运用SimulationX对系统建模和仿真。The vibratory theory is applied to the process of hydraulic excavator digging,which can not only reduce the digging resistance and energy consumption,but also improve the special operating ability （such as digging frozen soil） of the hydraulic excavator.Firstly,the vibratory excavation technology is introduced and the mechanism of reducing digging resistance is analyzed in this paper.On that basis,the vibratory excavation control system of the hydraulic excavator is researched and designed.The vibratory frequency and amplitude of the system can be adjusted timely according to different characteristics of working objects.Modeling and simulation are carried out by using SimulationX.
