本科毕业论文题目：大豆滚筒清选机传动结构设计学生姓名 届 2016 学 院 机械工程 专业 机械设计制造及其自动化 指导教师 职称 助教 下达任务日期 2015年12月1日 PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT I摘 要大豆滚筒清选机作为农业机械的一种，现在已经越来越普遍地应用到农业的大生产中。国内大豆滚筒清选机的研发及制造要与全球号召的高效经济、安全稳定主题保持一致。近期对机械行业中大豆滚筒清选机的使用情况进行了调查，发现在农业机械行业中，对于大豆等农作物的清选，如果在清选时使用临时设备清选，不但劳动强度太大而且工作效率极低，所以设计一个专用的大豆滚筒清选机势在必行。本文运用大学所学的知识，提出了大豆滚筒清选机的结构组成、工作原理以及主要零部件的设计中所必须的理论计算和相关强度校验，构建了大豆滚筒清选机总的指导思想，从而得出了该大豆滚筒清选机的优点是高效，经济，并且运行平稳的结论。关键词：大豆滚筒清选机；农业机械；设备；高效全套图纸，加153893706 PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT IIABSTRACTWith development of all kind of science technology and global economy, F manipulator is a automated 16 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 heay 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 atcompress engt hthdirec tionpro cedurework.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
