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.

手机号码专卖 看来楼上的二位不是这个专业的，所以翻译很不正确，我来翻译吧.先翻译名词解释：pr--控制部件名，意思为“转子功率”，ps--控制部件名，意思为“定子功率”，tm--机械转矩,ωs--定子(磁场)旋转角速度，dc bus--直流控制器，cgrid--部件名称，可能是“网储能器”的意思，pgc--指cgrid的功率或能量，ac/dc/ac converter--交（流）-直（流）-交（流）转换器（通常叫“交直交转换器”，或直接叫“变频器”），crotor--部件名，通常情况下，转差率值是绝对小于1的（该文章中的电机是异步电机，所以有这么一说），因此，pr相当于ps的一部分。既然tm对电能的产生是正向的（指机械转矩产生电能），且定子磁场的转向对恒频网压也是正向的和不变的，那么pr（转子功率）信号就是转差信号的一部分。pr相对转差的负差也是正值--转速比同步转速高（异步发电机转子的转速要比发电机的同步转速高），那么它对于转差的正值形成负差。当超同步转速运转时（指高于同步转速），pr将功率（电能）转移给dc bus（直流控制器）的电容器上，使得（输出）电压提高。对于亚（低于）同步转速运行时，pr从dc bus的电容器上吸收功率，使得输出电压降低。cgrid的作用就是：产生或吸收功率pgc(参照名词解释)，以保持直流电压不变。交直交转换器的稳态损耗与pr相等，风轮的转速由受控的pr吸收或产生的能量来确定。以下为对（输出）功率控制的解释。交流电的相序由crotor来控制，在超同步转速时为正向，亚同步转速时为负向。电压频率等于网频率与转差率的绝对值的乘积。crotor与cgrid具有产生或吸收无功功率的功能，它们可以用来控制（电）网终端的无功功率和电压。
