液压技术的快速发展给我国高空作业车的开发、研制奠定了技术基础。通过对高空作业车的整体设计要求，完成了对高空作业车主要装置和与其对应的液压系统的设计。曲臂式高空作业车由底盘、动力系统、液压系统、扩桥装置、转向装置、回转装置、变幅装置、伸缩臂装置、调平装置、作业斗摆动装置和电控系统等构成。根据控制系统需要控制的执行元件较多、多个执行元件需要比例控制的特点，系统采用了内置比例流量阀的插装阀块的控制形式实现对工作装置多任务协调控制的控制要求。作为独立驱动车辆，行走驱动系统的设计是本车的关键技术之一。为了实现行走系统的远程调速性能以及实现节能高效、稳定的性能，采用了变量泵控双速马达的液压闭式回路作为行走驱动系统的回路形式。依据液压系统的设计原理，详细探讨了曲臂式高空作业车液压系统的设计方法，为各种类型高空作业车液压系统的设计提供了一个完善的设计方法和平台。

The rapid development of hydraulic technology makes firm or stable the technical basis for developing aer-ial vehicles. By aerial overall design requirements, the completion of aerial main unit and its corresponding hydrau-lic system are designed. Crank aerial vehicles are made up the chassis, power systems, hydraulic systems, expanding the bridge device, steering device, turning device, luffing devices, telescopic device, leveling device, the job bucket swing devices and electronic control systems and other accessories. The actuator control system needs more control and needs more proportional control actuator characteristics, the system uses a form of control cartridge valve block built proportional flow control valve to achieve the requirements of the work unit coordinated control of multi-task-ing. As an independent driver of the vehicle, walking drive system design is one of the key technologies of the vehi-cle. In order to achieve remote speed performance running the system and achieve energy efficiency, stable perfor-mance, we use a variable displacement pump hydraulic closed loop control circuit in the form of a two-speed motor drive system as walking. In this paper, based on the design principle of the hydraulic system, a detailed discussion of the crank-propelled aerial work vehicle hydraulic system design approach is introduced, which provids a comprehen-sive design methodology and platform for the design of all types of aerial vehicles hydraulic system.
