摘 要

安全是一直以来人们关注的话题，在国家的安全观里主要以大局为重，而对于个人而言，自身和家人的安全是需要注意和关心的点。汽车的大量普及直接关系到个人和他人的安全。与生活息息相关的就是行车安全，包括他人和自身在行车过程的安全性至关重要，而汽车的行驶安全性是需要考虑的。为此，从汽车的行驶是否足够安全是主要切入点，而其中的制动性能是研发人员一直以来研究的热点。

本文主要以宝骏560车型的整车参数为依据，对汽车后轮盘式制动器进行设计。首先是汽车制动器的关键参数的确定，例如同步附着系数、制动力分配系数和最大制动力矩等。其次是根据参数来选择和确定制动器关键部件的构造参数，例如制动盘直径、厚度和制动块的尺寸参数和构造等，并以此为基础对盘式制动器的主要构件实现参数化建立模型。最后是对盘式制动器的制动性能进行分析，主要是车辆制动的加速度和制动行驶距离、制动方向稳定性，还有摩擦衬块和制动盘受热的稳定性等。

本文的研究成果在于拥有完善的盘式制动器设计计算过程，并将计算结果进行实体化建模，结合现代化的工程软件技术CAD中的catia软件将计算参数录入计算机，实现三维化。建立的模型可用于CAE、CAM对其热力分析、结构分析等性能分析，为此盘式制动器的优化提供数据资料。在设计过后的性能分析中，该盘式制动器在制动减速度、制动距离等方面均满足国家规定，设计合格。

本文的主要特点是在盘式制动器基础设计计算上，结合计算机辅助设计CAD技术进行设计，并且能够直接形成工程制图，不同于过去工程设计中的手绘，有效地提高了盘式制动器设计过程的效率，并且修改方便，能够结合CAE/CAM进行性能分析、结构优化等，给开发研究人员提供依据。

Abstract

Security has always been a topic of concern, in the national security concept, the main situation is the overall situation, and for individuals, the safety of themselves and their families is a point of attention and concern. The popularity of automobiles is directly related to the safety of individuals and others. What is relevant to life is the safety of driving, including the safety of others and their own driving process, and the driving safety of the car is to be considered. For this reason, from the safe driving of the car as the main breakthrough point, and the braking performance of automotive research and development staff has been the focus of research.

In this paper, the rear wheel disc brake is designed based on the vehicle parameters of Bao Jun 560 model. First of all, the key parameters of the automobile brake are determined, such as the coefficient of synchronous adhesion, the coefficient of braking force distribution and the maximum braking torque. The parameters of the key components of the brake are selected and determined according to the parameters, such as the diameter and thickness of the brake disc and the size parameters and construction of the brake block. Based on this, the main components of the disc brake are parameterized Three-dimensional model. Finally, the braking performance of the disc brakes is analyzed, mainly the braking deceleration and braking distance, the stability of the braking direction and the stability of the brake heat.

The research results of this paper are to have the perfect calculation process of disc brakes, and entity model is established according to the calculation results, the parametric model is established combined with the engineering CAD software technology in the modern CATIA software, to achieve two-dimensional to three-dimensional parameters. The established model can be used to analyze the performance of CAE and CAM, and provide a model for the optimization of disc brakes. In the performance analysis after the design, the disc brake in the brake deceleration, braking distance and so on are in line with national regulations, design qualified.

The main characteristic of this paper is the design and calculation of disc brake foundation, combined with computer aided design, CAD technology. This model can direct the formation of drawings, different from the past in the engineering design drawing, which greatly improves the design efficiency of disc brake, and easy to modify, can be combined with CAE/CAM performance analysis, structure optimization, and provide the basis for the development of model according to the number of researchers.
