车载机械自动调平机械系统设计与开发
摘    要
本论文的题目是车载机械自动调平机械系统设计与开发。论文分为选题背景、方案论证、过程论述、结论总结四大部分。
   选题背景部分，我主要讲述了本设计课题的来源、目的、意义、应解决的问题及应该达到的技术要求和介绍系统其它结构。还简述了本课题在国内外的发展概况，为设计提供了指导思想。
方案论证部分，我按照技术要求，对液压系统进行了分析，并设计了一套液压控制系统。
过程论证析部分，我考虑了整个雷达受到本身重力和风力的影响，为了保证力学稳定性，使用了塔架杆来支撑主升油缸。我综合考虑了液压缸举升的高度和缸需要提供的动力，结合工作环境，从而选择了四级液压缸作为主升油缸。液压缸举升1.5吨的雷达和1.5吨的塔架，再加上受风力的影响，这对主升油缸的强度提出了要求，本部分通过计算可以确定满足强度要求的缸的内外径。塔架设计部分，设计了塔架三节每节的尺寸，以及塔架各节的连接。
设计总结部分，我对本次设计过程进行了深刻的总结，为自己所学到了系统的分析问题而高兴，再次感受那些思考问题的过程与方法。

关键词：四级液压缸；雷达；设计；自动调平系统。

Abstract
The topic of my paper is vehicle-mounted machine automatically transferred Ping mechanical systems design and development. This paper is divided into four parts: selection of subjects background, programme appraisal, process expositions, conclusions summarized
   Selection of subjects background part, I described the main source of design topics, objectives, significance, and should be addressed to the technical requirements and other structures on the system. Also on the topic of development profile at home and abroad, providing guidance for the design ideas.  Because the whole radar antenna will be affected by the weight and wind, in order to make sure the mechanics stability, then the solution is by using tower frame pole to support the main promoting cylinder. The second part is just the analyses on the mechanics capability of the tower frame pole.
  Programme appraisal part of the question, I analysed the hydraulic system in accordance with the technical requirements, and to design a set of hydraulic control systems.
Analysis of the process of verification part, I consider the entire radar by itself gravity and wind effects. In order to ensure the stability of mechanics,I use the tower to support the main  hydraulic cylinder. On the part of the mechanics tower pole performance analysed.I integrated into the hydraulic cylinder up-down and hydraulic cylinder need to provide the high momentum in the work environment, thus chosen as a main or 4 hydraulic cylinder. 1.5 tons of hydraulic cylinder up-down radar and 1.5 tons town coupled with the impact of the wind, which the intensity of the fuel hydraulic cylinder or the demands of this segment by calculating the intensity can meet the requirements of main hydraulic cylinder. In the conclusion, I give a thorough summing-up of the process of my project. I feel pleased that I have learned to analyze problem generally, and have reconsidered the methods and process of my project. Tower design part, I use the second part of the contents , designed tower section three dimensions, and the tower sections connected.
In the conclusion, I give a thorough summing-up of the process of my project. I feel pleased that I have learned to analyze problem generally, and have reconsidered the methods and process of my project.
Key word: triple-level hydraulic cylinder ；design ；Radar；automatically leveling system.
