摘　　要：介绍转阀控制的高频液压激振器的系统组成和工作原理,建立了系统的数学模型,并用AMESim软件对系统进行了仿真分析。得出供油压力、马达转速与激振器激振幅值的关系,通过改变系统的供油压力或马达的转动频率,即可方便地实现对激振器幅值的改变,进而实现对激振力的控制。通过对该系统的仿真研究,为该液压激振器的设计应用和性能改善提供了理论依据。A kind of hydraulic exciter based on rotary valve control was studied, the composition of the exciter and its working principle were introduced, and the mathematical model of the system was established. The characters of the system were simulated using AMESim. From the results of the simulation, get the relationship of the amplitude of vibration oil cylinder between the sys- tem＇ s pressure and the exciting frequency. The results can provide theoretical bases to design the hydraulic exciter.
