附录A 外文文献 Electric Power Steering system 1.History In automobile development course, Steering system experienced four stages of development: from the initial mechanical Steering system (for your DNS setting Steering, abbreviation ) development for Hydraulic Steering system (Hydraulic Power Steering, abbreviation HPS), then again appeared electronically controlled Hydraulic Steering system (Electro Hydraulic Power Steering, abbreviation EHPS) and Electric Power Steering system (Steering, room Power as EPS). Assemble mechanical steering system of car parking and low-speed driving, when the driver's steering control burden too heavy, in order to solve this problem, the American GM in the 1950s took the lead in the car hydraulic steering system. But, hydraulic steering system can't juggle vehicles to speed portability and high speed, so the steering stability Koyo in Japan in 1983, with the company introduced the application of speed sensing function of hydraulic steering system. This new type of steering system can provide speed increased with the decreasing steering, but complicated structure, cost is higher, and cannot overcome hydraulic system itself has many shortcomings, is a cross between a hydraulic steering and electric power steering the transition between the products. In 1988, Japan Suzuki company first in small cars equipped with Cervo Koyo company development on the steering column, power type electric power steering system; In 1990, Japan Honda NSX in sports car company adopted self-developed rack power type electric power steering system, henceforth unveils the electric power steering in cars applications history 2.Working principle Electric power steering system are as follows: first, the working principle, torque sensor measured on steering wheel drivers on the manipulation of the moment, the wheel speed sensors detect the vehicle driving speed, then present the two signals to ECU; According to the built-in control strategy: ECU, calculates the ideal target booster torque, into current instructions to motor; Then, the power generated by the torque motor slowdown institutions amplification on steering system in mechanical manipulation of the moment, and the driver together to overcome resistance torque, realize to the vehicle steering. 3.

转向系统设计与优化 摘要 汽车在行驶过程中，需要按照驾驶员的意志经常改变行驶方向，即所谓汽车转向。用来改变或保持汽车行驶方向的机构称为汽车转向系统。汽车转向系统的功能就是按照驾驶员的意愿控制汽车的行驶方向。汽车转向系统对汽车的行驶安全是至关重要的。因此需要对转向系统进行优化，从而使汽车操作起来更加方便、安全。本次设计是EPS电动转向系统，即电动助力转向系统。该系统是由一个机械系统和一个电控的电动马达结合在一起而形成的一个动力转向系统。EPS系统主要是由扭矩传感器、电动机、电磁离合器、减速机构和电子控制单元等组成。驾驶员在操纵方向盘进行转向时，转矩传感器检测到转向盘的转向以及转矩的大小，将电压信号输送到电子控制单元，电子控制单元根据转矩传感器检测到的转距电压信号、转动方向和车速信号等，向电动机控制器发出指令，使电动机输出相应大小和方向的转向助力转矩，从而产生辅助动力。汽车不转向时，电子控制单元不向电动机控制器发出指令，电动机不工作。该系统由电动助力机直接提供转向助力，省去了液压动力转向系统所必需的动力转向油泵、软管、液压油、传送带和装于发动机上的皮带轮，既节省能量，又保护了环境。另外，还具有调整简单、装配灵活以及在多种状况下都能提供转向助力的特点。因此，电动助力转向系统是汽车转向系统的发展方向。 关键词：机械系统，扭矩传感器，电动机，电磁离合器，减速机构，电子控制单元。
机械类汽车转向系统外文文献及翻译
1 Introduction The key task for the automobile industry and its suppliers in future lies in speedily developing and implementing ecologically sound and economically justifiable mobility systems. Light metals such as aluminum and magnesium along with glass and carbon fiber reinforced materials, ceramics and composites have opened up the potential for considerable weight reduction and for "green" vehicle concepts which can be realized economically. Aluminum in particular can provide the impetus for new designs for the next millennium. Decades ago, the use of aluminum in auto construction was seen as an "experiment"; Today it is a vital factor in reducing weight and thus lowering fuel consumption. The average passenger car today contains 60 to 70 kg of aluminum, and current developments point to a doubling of this amount in the next few years. Motor vehicles both now and in future must meet requirements for: greater performance, greater safety, comfort, low pollution. Lightweight construction is not just about reducing weight; it is a question of -striking the right balance between reduced weight and structural efficiency. In vehicle construction this normally means making the best use of the generally very tight space available for individual components so as to allow weight to be minimized while still meeting all stiffness, strength, natural frequency or acoustical requirements. To achieve this, stresses must be distributed throughout the structure as evenly as possible. Modern numerical analysis methods such as FEA allow a very detailed analysis of system behavior, provide cost-efficient support for the complex process of optimization and thus make a huge contribution to advances in lightweight construction. Packaging, safety considerations, reproducibility and price place restrictions on the degree of weight reduction achievable. The broad range of expertise available to Krupp Presta AG allows the company to analyze customer specifications for steering systems and provide appropriate solutions. 2 Requirements to be met by steering systems The steering is an important part of the feel of a car. The steering system should make driving an enjoyable experience with no unpleasant vibration from the road surface while guaranteeing the required hand- sing. It is also important that high safety requirements be met, both under normal conditions and in crash situations. The key criteria for the steering system are thus as follows:rolling friction, torsional stiffness /strength, Damping, temperature, corrosion, durability / fatigue, weight. Crash kinematics and energy absorption steering column requirements:natural frequency / stiffness, mass, damping, space, strength (crash, misuse), ergonomics, handling, acoustics, crash kinematics and energy absorption. Other basic conditions:interfaces with adjacent components, installation, joining techniques, price. 3 Materials material light weighting can be achieved by using either stronger or lighter material. When stiffness or natural frequency are Important sizing criteria, low density materials with a high modulus of elasticity by quired. Non-exotic materials must be selected which are readily recyclable, low in price and display good durability.Further requirements are set by the manufacturing and joining processes. Steel, aluminum, magnesium and a variety of plastics are the materials of choice for steering systems.

转向器英文文献翻译
Electronic power steering system What it is： Electrically powered steering uses an electric motor to drive either the power steering hydraulic pump or the steering linkage directly. The power steering function is therefore independent of engine speed, resulting in significant energy savings. How it works : Conventional power steering systems use an engine accessory belt to drive the pump, providing pressurized fluid that operates a piston in the power steering gear or actuator to assist the driver. In electro-hydraulic steering, one electrically powered steering concept uses a high efficiency pump driven by an electric motor. Pump speed is regulated by an electric controller to vary pump pressure and flow, providing steering efforts tailored for different driving situations. The pump can be run at low speed or shut off to provide

汽车悬架系统中英文对照外文翻译文献
汽车悬架系统中英文对照外文翻译文献(文档含英文原文和中文翻译) 汽车悬架 现代汽车中的悬架系统有两种，一种是从动悬架，另一种是主动悬架。 从动悬架即传统式的悬架，是由弹簧、减振器（减振筒）、导向机构等组成，它的功能是减弱路面传给车身的冲击力，衰减由冲击力而引起的承载系统的振动。其中弹簧主要起减缓冲击力的作用，减振器的主要作用是衰减振动。由于这种悬架是由外力驱动而起作用的，所以称为从动悬架。 而主动悬架的控制环节中安装了能够产生抽动的装置，采用一种以力抑力的方式来抑制路面对 车身的冲击力及车身的倾斜力。由于这种悬架能够自行产生作用力，因此称为主动悬架。 主动悬架是近十几年发展起来的，由电脑控制的一种新型悬架，具备三个条件： （1）具有能够产生作用力的动力源；
（2）执行元件能够传递这种作用力并能连续工作； （3）具有多种传感器并将有关数据集中到微电脑进行运算并决定控制方式。因此，主动悬架汇集了力学和电子学的技术知识，是一种比较复杂的高技术装置。 例如装置了主动悬架的法国雪铁龙桑蒂雅，该车悬架系统的中枢是一个微电脑，悬架上有5 种 传感器，分别向微电脑传送车速、前轮制动压力、踏动油门踏板的速度、车身垂直方向的振幅及频率、转向盘角度及转向速度等数据。电脑不断接收这些数据并与预先设定的临界值进行比较，选择相应的悬架状态。同时，微电脑独立控制每一只车轮上的执行元件，通过控制减振器内油压的变化产生抽动，从而能在任何时候、任何车轮上产生符合要求的悬架运动。因此，桑蒂雅桥车备有多种驾驶模式选择，驾车者只要扳动位于副仪表板上的“正常”或“运动”按钮，轿车就会自动设置在最佳的悬架状态，以求最好的舒适性能。 另外，主动悬架具有控制车身运动的功能。当汽车制动或拐弯时的惯性引起弹簧变形时，主动悬架会产生一个与惯力相对抗的力，减少车身位置的变化。例如德国奔驰2000 款CL 型跑车，当车辆拐弯时悬架传感器会立即检测出车身的倾斜和横向加速度，电脑根据传感器的信息，与预先设定的临界值进行比较计算，立即确定在什么位置上将多大的负载加到悬架上，使车身的倾斜减到最小。 汽车主动悬架—液压和空气式 从控制力的角度划分，悬架可分为被动悬架，半主动悬架和主动悬架。目前，大多数汽车的悬架系统装有弹簧和减振器，悬架系统内无能源供给装置，其弹性和阻尼不能随外部工况变化，因此称这种悬架是被动悬架。 主动悬架有作为直接力发生器的动作器，可以根据输入与输出进行最优的反馈控制，使悬架有最好的减震特性，以提高汽车的平顺性和操纵稳定性。它由弹性元件C和一个力发生器Fe组成。 半主动悬架可看作由可变特性的弹簧和减振器组成的悬架系统，虽然它不能随外界的输入进行最优的控制和调节，但它可按存储在计算机的各种条件下最优弹簧和减振器的优化参数指令来调节弹簧的刚度和减振器的阻尼状态。它由弹性元件 C 和一个一个阻尼系数能在较大范围内调节的阻尼器组成。

1 引言 1.1汽车转向系统简介 汽车转向系统，顾名思义是为了能够使车辆按照驾驶员的意愿向左或者向右转弯或者直线行驶。转向装置有很多种，也一直在经历一个循序渐进不断更新不断创新的过程。从发明家本茨发明汽车的初期，转向系统知识最简单的形式来转向，其机构为单纯的扶把式，没有助力，所以笨重，费力，以及行驶状态不稳定。从在原始的雏形开始，各国人士不断创新改革，到现在为止，汽车转向系统的应用按先后顺序可以分为：机械转向装置、液压助力转向装置、电子控液压助力转向系统、电助力转向系统、四轮转向系统、主动前轮转向系统和线控转向系统[1]目前市场大部分中低档轿车采用的液压式转向器，当然电控的也很常见，所以在该种系统的转向器技术的发展如今已经遇到了瓶颈。随着人们对乘车舒适，节能，安全，稳定的期望，电控液压式转向系统逐渐取代了先前的版本，但随着科技的进步，越来越多的科学家期待有路感的转向系统问世，所以流量阀式液压助力转向器出现了，在不同车速下，驾驶员手握方向盘，感觉到了路感的存在，助力特性曲线描述的就是“路感”，但是美中不足的是这种液压式转向器依然存在很多缺陷，电机，液压泵，转向器，流量阀等等转向器在发动机旁的布置问题又出现了，还有就是液压油的泄漏问题越来越的突出尖锐。电助力EPS （Electronic Power steering system）是在纯机械转向机构的前提下，设计加装了扭矩和车速等信号传感器、电子控制单元和转向助力装置等[2]。所以电助力式转向器弥补了上述的不足，而且节能环保，易于线性控制，所以现在很多研究人员把目光转向了电助力式转向机，瞬时其成为了国际汽车工业转向系统新的研究主题，且这种系统也正在慢慢实现整车量产状态。

The machinery steering system is refers by pilot's physical strength achievement changes the energy, in which all power transmission all is mechanical, the automobile changes the movement is operates the steering wheel by the pilot, transmits through the diverter and a series of members changes the wheel to realize. The mechanical steering system by changes the control mechanism, the diverter and major part changes the gearing 3 to be composed. Usually may divide into according to the mechanical diverter form: The gear rack type, follows round the world -like, the worm bearing adjuster hoop type, the worm bearing adjuster refers sells the type. Is the gear rack type and follows using the broadest two kinds round the world -like (uses in needing time big steering force).In follows round the world -like in the diverter, the input changes the circle and the output steering arm pivot angle is proportional; In the gear rack type diverter, the input changes the turn and the output rack displacement is proportional. Follows round the world -like the diverter because is the rolling friction form, thus the transmission efficiency is very high, the ease of operation also the service life are long, moreover bearing capacity, therefore widely applies on the truck. The gear rack type diverter with follows round the world -like compares, the most major characteristic is the rigidity is big, the structure compact weight is light, also the cost is low. Because this way passes on easily by the wheel the reacting force to the steering wheel, therefore has to the pavement behavior response keen merit, but simultaneously also easy to have phenomena and so on goon and oscillation, also its load bearing efficiency relative weak, therefore mainly applies on the compact car and the pickup truck, at present the majority of low end passenger vehicle uses is the gear rack type machinery steering system. Along with the vehicles carrying capacity increase as well as the people to the vehicles handling quality request enhancement, the simple mechanical type steering system were already unable to meet the needs, the power steering system arise at the historic moment, it could rotate the steering wheel while the pilot to provide the boost, the power steering system divides into the
