1、 1 摘摘 要要 将液压缸提供的液压能重新转换成机械能的装置称为执行元件。 执行元件是直接做功者，从能量转换的观点看，它与液压泵的作用是 相反的。 根据能量转换的形式， 执行元件可分为两类三种： 液压马达、 液压缸、和摆动液压马达，后者也可称摆动液压缸。液压马达是作连 续旋转运动并输出转矩的液压执行元件； 而液压缸是作往复直线运动 并输出力的液压执行元件。本说明书根据前人设计好的液压缸， 设定 一定的工作压力和载荷，根据液压缸的材料，用手工计算和软件编程 的方法分别校核缸筒内径，壁厚，活塞杆的稳定性，抗爆能力等，并 设计快进、工进、快退系统图，选择液压阀的型号，完成课程设计的 教学要求。 关键

Work is a direct implementation of components, from the point of view of energy conversion; it is the role of the hydraulic pump opposite. According
3、to energy conversion in the form of implementation of the three components can be divided into two categories: hydraulic motors, hydraulic cylinders, hydraulic motors and swing, which may also be said swing hydraulic cylinder. Hydraulic motor is the continuous torque and rotational movement of the h
4、ydraulic actuators, and hydraulic cylinder is a reciprocating linear motion and the output of the hydraulic components. And this statement according to the designed hydraulic cylinders，set a work pressure and load，according to the materials of hydraulic cylinder, with manual calculation and software programming method, check cylinder diameter and thickness, the stability of the piston rod, anti-explosion ability, and designed for fast forward, the Progressive, fast forward, and other moveme
