1、课题:轿车制动系统设计及分析本次设计针对A8轿车的制动系统进行设计分析,能够有效保证制动系统的系统,分析了解制动系统的结构形式和参数。通过设计,能够全面系统了解制动系统乃至车辆的设计计算方法。对轿车制动系统的研究现状进行系统全面的分析,主要包括轿车制动系统的设计分析目的意义,轿车制动系统主要研究成果,轿车制动系统未来的发展趋势等;然后对盘式轿车制动系统总体方案设计,确定盘式轿车制动系统的结构形式,本次设计确定的轿车制动系统的结构形式为浮动钳通风盘式结构形式,并进一步明确轿车制动系统的具体结构形式,主要组成包括了制动管路、制动主缸、制动钳部分、制动支架结构等。基本原理是采用液压驱动形式,实现从主
2、缸到制动器轮缸的压力传递,然后通过摩擦片挤压制动盘产生摩擦力,完整制动过程。对轿车制动系统的具体传动结构及参数进行设计计算,主要包括轿车制动系统的制动力分配、制动器的重点结构如制动钳、摩擦片、制动盘的具体结构和强度设计校核等。通过三维软件对轿车制动系统进行了造型设计,然后完成了二维图纸的绘制。通过对关键部件的有限元分析,熟悉和掌握了有限元法分析的方法和应用。关键词:轿车;盘式;制动器;三维;有限元;分析AbstractThis design is designed and analyzed for the A8 braking system of the car, which caneffec
3、tively guarantee the system of the braking system, and analyze and understand thestructure and parameters of the braking system. Through design, we can comprehensivelyunderstand the design and calculation methods of the braking system and even the vehicle.Carry out a systematic and comprehensive ana
4、lysis of the research status of car brakingsystems, including the purpose and significance of design analysis of car braking systems, themain research results of car braking systems, the future development trend of car brakingsystems, etc.; The overall scheme design of the dynamic system determines
5、the structuralform of the disc brake system. The structural form of the car brake system determined in thisdesign is the floating caliper ventilated disc structural form, and the specific structural form ofthe car brake system is further clarified. The main components include brake pipeline, brakema
6、ster cylinder, brake caliper part, brake support structure, etc. The basic principle is to adoptthe hydraulic drive fonn to realize the pressure transmission from the master cylinder to thebrake wheel cylinder, and then the friction lining squeezes the brake disc to generate friction,which completes
7、 the braking process. Design and calculation of the specific transmissionstructure and parameters of the car brake system, mainly including the brake force distributionof the car brake system, the key structures of the brake such as the specific structure andstrength design check of the brake calipe
