汽車是在現今的工作生活中已經成為主要的交通工具，給出行的人們帶來了很大的便利，但是汽車的安全問題始終是人們關注的。制動系統是對汽車進行制動的，以達到低速或者停止，在遇到緊急情況時就得得益于汽車制動系統。制動系統的好壞直接影響了汽車的整體性能，沒有好的制動性能汽車其他方面的性能也跟不上去，是一種相輔相成的關系。汽車制動系統是由各個制動部件組合而成，每個部件的性能的好壞勢必影響整個系統的性能。所以對汽車制動系統性能的檢測至關重要。
這篇論文主要介紹了汽車制動系統的組成部分之一——帶主缸的助力器在三個不同溫度（高溫、常溫、低溫）狀態下測試其耐久度即壽命的檢測臺。該測試臺是根據真空助力器模擬試車狀態下設計的，試驗裝置包括傳動機構，工裝夾具部分，起氣動部分，還有液壓輸出部分，基本按照模擬試車狀態，已達到更準確反映產品的質量。該設備夾具簡單換裝產品方便，借助氣動產生可控輸入力，利用液壓產生輸出力經過處理顯示在工控機的顯示屏上更直觀的反應助力器在各個工作狀態。總體來說，該設備設計新穎，安裝方便，通過電氣控制使其操作方便，數據反映更直接。
本次設計主要完成檢測汽車真空助力器帶主缸總成常溫及高低溫工況下耐久性能所需要的機械部分，包括產品的裝夾，動作。除了對設備的可靠性設計，元器件的質量與可靠性水平是影響設備質量與可靠性水平的重要因素。元器件的質量與可靠性水平是設備質量與可靠性水平的基礎， 要提高設備的可靠性，必須重視元器件的質量與可靠性。通過此次設計進一步了解和深入研究機電一體化產品的相關開發設計。

Abstract
Today Car is the main means of transportation for people’s working life, give a great deal of convenience for people traveling, but the car’s safety always have been people's attention. Braking system for braking of the car in order to achieve low-speed or stop, when in cases of emergency situation would have benefited from the vehicle. Good or bad Braking system is direct impact on the overall performance of the car. No good on braking performance, vehicle performance in other areas can not keep with, this is a complementary relationship. Automotive braking system is a combination of the various brake parts, the performance of each component is bound to affect the quality of the performance of the entire system. Therefore, the testing automobile brake system performance is very essential
This paper introduces one component of car’s braking system - booster with the master cylinder’s life in three different temperatures (high temperature, room temperature, low temperature). The test is designed under simulation test booster vacuum, test equipment including transmission, fixture parts, pneumatic parts, the hydraulic output, The basic state in accordance with the simulation test, has reached more accurately reflect the products quality. Simple fixture of the equipment is easy to change products , controllable input generated by aerodynamic forces, the use of hydraulic power output have been processed displayed on the screen IPC more intuitive booster response in all working condition. Overall, the equipment design, installation convenience, it is easy to operate through the electric control, the data reflect more direct.
This design is the mechanical parts which the booster with the master cylinder’s life needed. It is including the products of the clamping production. In addition to the reliability of the equipment, component quality and reliability levels are important factor to affect the level of equipment quality and reliability. to improve the reliability of equipment, must pay attention to the quality and reliability of components. Through this design, We can in-depth research more about the mechatronics product’s development and design.
