摘　　要：针对传统液压激振器频率及负载难以提高的问题,提出一种阀芯回转式液压激振器。介绍了阀芯回转式液压激振器系统组成及工作原理,建立系统数学模型,利用AMESim软件对系统进行仿真分析,得到不同阀芯转速、供油压力、负载下系统的动态特性。结果表明:改变电机转速、供油压力,即可对激振器的振幅幅值、速度、加速度、激振力进行控制;负载的大小对该激振器整体性能影响较小。通过对该激振系统的仿真研究,为设计高负载高频率的液压激振器提供了理论依据。It is difficult to improve frequency and load of a traditional hydraulic exciter.In order to solve this problem,a spool rotary hydraulic exciter is proposed.The system composition and working principle of the spool rotary hydraulic exciter are introduced.The mathematical model of the system is established.The system is simulated and analyzed with AMESim software to obtain the dynamic characteristics of the system with different spool speed,pressure of the supplied oil and load.The results show that the amplitude,speed,acceleration and exciting force of the exciter can be controlled by changing the motor speed and pressure of the supplied oil;the magnitude of the load has little effect on the overall performance of the exciter.Through the simulation study of the excitation system,it provides a theoretical basis for designing high-load and high-frequency hydraulic vibration exciters.
