摘     要
 汽车的安全性一直是汽车行业和全社会普遍关心的问题，要保证其在各种道路条件或复杂多变的交通状况下，随时改变汽车行驶的速度而且行车安全，关键取决于汽车制动系统的灵敏度和可靠性。制动系统是保证行车安全的至为重要的系统，制动性能的好坏还直接影响车辆的平均技术车速和车辆的运输效率，这也是保证运输经济效益的重要因素。而制动主缸是汽车制动系统的液压传动装置中保障汽车行驶安全性的重要部件。
 本文首先对车辆制动系性能进行分析，分析介绍了制动系的制动原理及功用，其次对制动主缸的一些结构尺寸进行了计算，最后完成了制动主缸的设计。
 在此基础上还运用UG对制动主缸进行三维设计，并且还根据一些三维实体模型对制动主缸的第二活塞的运行速度进行了性能仿真。

The Design and Emulation of the brake master cylinder

 Abstract
 The automobile security always is the automobile profession and the entire society universal issue of concern,if we want to change the speed and drive safely at any time when we are in each kind of path condition or the complex changeable transportation condition,it depends on the vehicle braking system sensitivity and reliability. The braking system which guarantees the traffic safety is a important system, the braking quality also directly affects the average technical vehicle speed and the vehicles transportation efficiency it is also a important factor Which guarantees the transportation economic efficiency. The brake master cylinder is a important part in the automobile braking system hydraulic gear, which guarantees the automobile travel safely.
 This article first carries on the analysis to the vehicles braking system performance and introduce the brake principle and the function of the braking system. Next calculate the size of the brake master cylinder .Finally complete the brake master cylinder design.
 I also use UG to carry on doing the three dimensional design to the brake master cylinder on this basis,and doing the performance simulation of the speed of the second brake master cylinder piston according to some three-dimensional solid models.
