顺序阀的设计
摘 要
本课题来源于当今社会液压元件的创新和更新换代基础之上，通过设计出顺序阀，从而来满足当今社会液压元件更新换代能力不足的缺陷。
顺序阀是直接压力-弹簧平衡式的压力控制阀门，也称压力阀。机床上的元件先定位后夹紧的液压系统中常用顺序阀控制。专用车床的横向和纵向进给液压缸的顺序动作实例，其顺序动作是：①车刀先横向进给；②纵向进给；③横向退刀；④纵向退刀。它用油路本身的压力来控制顺序阀或者液马达的动作顺序，以实现油路系统的自动控制。
本文运用大学所学的知识，了解顺序阀的工作原理，在此基础上，设计一款顺序阀。该顺序阀的工作介质为12MPa的液压油，主要用来控制液压缸(或液压马达)的顺序动作，此外，还可作卸荷阀、背压阀和平衡阀用。通过查找相关料，了解顺序阀的内部结构和工作原理，从而构建了顺序阀组成结构的总的指导思想，从而得出了该顺序阀的优点是高效，经济，并且传动效果好，运行平稳的结论。

Abstract
With development of all kind of science technology and global economy, Pneumatic manipulator is a automated devices that can mimic the human hand and arm movements to do something，aslo can according to a fixed procedure to moving objects or control tools. It can replace the heavy labor in order to achieve the production mechanization and automation, and can work in dangerous working environments to protect the personal safety.
Therefore widely used in machine building, metallurgy, electronics, light industry and atomic energy sectors.The pneumatic part of the design is primarily to choose the right valves and design a reasonable pneumatic control loop, by controlling and regulating pressure, flow atcompressedneceengththdirectionprocedurework.
The inverted pendulum is a typical high order system, with multi variable, non-linear, strong-coupling, fleet and absolutely instable. It is representative as an ideal model to prove new control theory and techniques. During the control process, pendulum can effectively reflect many key problems such as equanimity, robust, follow-up and track, therefore.This paper studies a control method of double inverted pendulum . First of all, the mathematical model of the double inverted pendulum is established, then make a control design to double inverted pendulum on the mathematical model, and determine the system performance index weightmatrix , by using genetic algorithm in order to attain the system state feedback control matrix.
