设计简介
摘要
在现代轿车日新月异的变革中，轿车的液压制动系统变得的越来越重要。轿车的安全性能逐渐成为消费者的购买轿车所要考虑的主要因素之一，因此轿车的液压制动系统的标准就被市场所定义更高层次，企业如果想让自己品牌的轿车占有量逐渐扩大，就不得不重视轿车上的制动系统，如此便构成轿车液压制动系统的性能良性改革。在轿车上运用Proe软件对所建立的三维立体模型进行仿真分析也已经被汽车行业所普遍使用，本文使用Proe软件对轿车液压制动系统的盘式制动器进行模型仿真以及运动分析。
本文针对轿车的液压制动系统做主要设计。对制动系统的主要部件进行选型或者设计计算，对盘式制动器进行Proe软件进行三维立体建模和运动仿真分析，来检测轿车液压制动系统的合理性以及可行性。

Abstract
In the ever-changing changes of modern cars, the car's hydraulic braking system has become more and more important. The safety performance of cars has gradually become one of the major factors for consumers to consider when buying cars. Therefore, the standard of the car's hydraulic braking system is defined by the market at a higher level. If companies want to expand their own brand of cars, It is necessary to pay attention to the braking system on the car, which constitutes a benign reform of the performance of the hydraulic braking system of the car. The use of Proe software in the car to simulate the three-dimensional model has also been widely used by the automotive industry. This paper uses Proe software to simulate and analyze the disc brakes of the car's hydraulic braking system.
This article mainly designs the hydraulic braking system for cars. The main components of the braking system are selected or calculated, and the Proe software of the disc brake is used for three-dimensional modeling and motion simulation analysis to check the rationality and feasibility of the hydraulic braking system of the car.
Key words: brake system; disc brake; simulation analysis
