摘  要

 本次畢業(yè)設(shè)計(jì)開發(fā)了剎車主缸密封檢測(cè)臺(tái)，用于檢測(cè)剎車系統(tǒng)中主缸的密封性能。完成了檢測(cè)臺(tái)系統(tǒng)整體結(jié)構(gòu)的設(shè)計(jì)，確定了硬件系統(tǒng)的組成和零部件。本課題中的機(jī)械部分以氣動(dòng)結(jié)構(gòu)為核心，利用觸摸屏與PLC作為中央處理核心。
 根據(jù)安裝好的設(shè)備以及控制流程圖提供的總體設(shè)計(jì)思路編寫了PLC程序，用于控制各執(zhí)行元件，實(shí)現(xiàn)了對(duì)主缸的高壓（主缸內(nèi)兩腔分別0.7MPa和0.5MPa），低壓（140KPa），以及端面密封（0.5MPa）的檢測(cè)。本課題開發(fā)的剎車主缸密封檢測(cè)平臺(tái)，可以實(shí)現(xiàn)對(duì)汽車剎車系統(tǒng)中主缸的密封性能檢測(cè)，多次測(cè)試表明本系統(tǒng)精度高、處理速度較快，達(dá)到了實(shí)時(shí)檢測(cè)的要求。

Abstract
 In this graduation design, I participate in a project to exploit Master Brake Cylinder Test-bed, which was used to detect seal capability of Master Brake Cylinder in brake system of automobile. We finished construction of the whole system design, and defined structure and spare parts of the hardware system. In this project we built pneumatic structure as the core of machinery parts, and touch screen compose PLC(Programmable Logic Controller) as the central processor.

 Under this fixed devices and flow chart which direct us the whole design scheme, we could program to control the other actuators. At last we should debugging the whole system, detect the Master Brake Cylinder in high pressure(each cavity inside the Master Brake Cylinder is 0.5MPa and 0.7MPa), low pressure(140KPa) and end sealing capability(0.5MPa).This Master Brake Cylinder Test-bed can detect seal capability of Master Brake Cylinder in brake system of automobile, times of tests showed the high accuracy and hyper processing speed of this system, reached the requirement of immediate detection.

Key words:  Sealing capability detection ；PLC ；Touch screen
