题目：华晨宝马齿轮齿条转向器的设计

摘要

本论文根据对齿轮齿条式转向器的研究以及资料的查阅，着重阐述了齿轮齿条

式转向器类型选择，不同类型齿轮齿条式转向器的优缺点和各种类型齿轮齿条式转

向器应用状况。根据原有数据计算转向系的传动比，并确定齿轮齿条的几何参数。

齿轮齿条式转向器总体设计，受力分析，及对齿轮齿条的疲劳强度校核、齿根弯曲

疲劳强度校核。修正齿轮齿条式转向器中不合理的数据。通过对齿轮齿条式转向器

的设计，选取出相关的零件如螺钉、轴承等，并在说明书中画出相关零件的零件图。

通过说明书并画出齿轮齿条式转向器的零件图。

本题目为设计类实际课题，来源于华晨宝马齿轮齿条式转向器的设计过程。我

国生产的宝马车齿轮齿条式转向器从仿制开始起步，近期产品的质量较早期有所提

高。但受国产配套件质量及设计水平等的影响，我国目前生产的宝马车的总体水平，

与进口产品及港口用户的要求仍有较大差距，齿轮齿条式转向器的生产也是如此，

为满足市场需求，特开发华晨宝马齿轮齿条式转向器。通过对华晨宝马齿轮齿条式

转向器的设计，能培养学生综合运用所学的基本理论、基本知识解决问题的能力，

培养学生英语阅读和翻译能力，学习专用汽车设计经验，掌握汽车设计基本方法。

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,atcompressedneceengththdirectionprocedurework.The inverted pendulum is a typ

ical 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 reflec

t 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 mod

el of the double inverted pendulum is established, then make a control design to double in

verted pendulum on the mathematical model, and determine the system performance index

weightmatrix , by using genetic algorithm in order to attain the system state feedback cont

rol matrix. Finally, the simulation of the system is made by . After several test matrix valu

e the results are not satisfactory response, then we optimize matrix by using Genetic Algor

ithm. Simulation results show: The system response can meet the design requirements effe

ctively after Genetic Algorithm optimization. Small twisted paper broken machine for

ordinary home, not only can be used for minced meat, can also be used with crushed

peanuts, crushed ice, spices and otherfood, small power requirements, powered by the

motor drive, reasonable structuredesign.
