哪位英文高手帮忙翻译以下摘要 非常感激
摘要：制动器是制动系统的重要组成部分，本论文主要介绍了商务车的制动器设计。从盘式和鼓式制动器的结构与性能对比入手，考虑到盘式制动器制动效能更好，且尺寸和质量都相对较小，散热性能好，且所设计商务车的发动机转矩和功率较大，车速较高，整体性能较好，属于中高档车，故本设计前后轮均选用了浮盘式制动器。
基本结构选定后本论文对制动器展开了以下设计。第一制动系的参数：包括制动力分配系数、同步附着系数、制动强度、附着系数利用率以及最大制动力矩等参数的选择计算；第二制动器及其零部件：制动盘、制动钳体、摩擦衬块等制动器零部件的尺寸计算与材料选择；第三驻车制动：本设计选用了后轮驻车制动，在后轮盘式制动器上加装了驻车制动的机械结构；第四制动驱动机构：制动轮缸、制动主缸、以及踏板行程的设计计算。
上述完毕后对所设计的制动器进行了制动减速度与制动距离的验算，对制动效能的稳定性以及制动时的方向稳定性进行了分析，并用MATLAB绘图功能绘制出了前后轴制动力分配曲线，上述均符合设计要求，验证了该制动器设计的合理性。最后，根据设计与计算用CAD绘制出了该商务车制动器的装配图和制动钳体、制动盘、活塞、摩擦衬块等零件图，并对其进行了三维建模。
除此之外，本论文简单介绍了制动驱动机构的结构型式选择，制动主缸，制动管路的多回路系统的选择以及制动器的研究现状及发展前景。

Brake is an important part of brake system, this paper mainly introduces the design/brake. From the drum brake disc and the structure and performance comparison, considering the disc-brake braking performance is better, and size and quality are relatively small, thermal performance is good, and the design/engine torque and power, high speed, good performance, belongs to high-grade car, so this design sense are chosen floating disc brakes. The basic structure of the selected papers on the brakes. First, the parameters of braking power distribution coefficient include: adhesion coefficient, synchronous adhesion coefficient, strength, and brake, and maximum braking torque parameters calculation, etc. The second brake and its components: the brake disc and calliper, friction lining block size of components etc brake calculation and material selection, The third in the design in the rear brake selection in the rear brake disc, install the parking brake on the mechanical structure, Fourth: brake wheel drive mechanism brake cylinder, the brake pedal stroke the cylinder, and the design calculation. After the design of brake on the brake speed and braking distance of braking performance, stability and the direction of braking stability is analyzed, with MATLAB graphics rendering the braking force distribution curve, above all comply with the design requirements, and verifies the rationality of the design of the brakes. Finally, according to the design and calculation using CAD drawing out the city of brake assembly and brake caliper disc brake, piston, liner, friction parts and pieces of the 3d modeling. In addition, this paper briefly introduces the drive mechanism brake type selection, brake main cylinder pipe, braking system, the selection of multi-loop research status of brake and development prospects.
