摘　　要：为进一步简化传统液压系统结构、提高工作效率,设计了一种将动力元件、执行元件和控制元件有机集成的完全一体化的内循环数字液压缸系统。分析了系统的工作原理,确定了系统的各种参数;并建立了系统的仿真模型,运用AMESim软件平台进行了仿真研究。研究表明:该系统在空间、重量受限的场合有较大的优势,可适用于低速、中低压系统。To further simplify the structure of traditional hydraulic system and improve its working efficiency, a dig ital hydraulic actuator system with inner circulation was designed, in which the power unit, actuator and control el ement are entirely integrated. The operational principle of the system is analyzed and all kinds of parameters of the system are determined. Simulation model of the system is established and simulations are performed by using AMES im software. The results show that the designed system has a great advantage in the situation with limited space and weight, and it is applicable for hydraulic systems of low speed and low or medium pressure.
