不转向的

Department of Electromechanics, NanChang University, Nan Chang, 330031, ChinaAbstract: In order to control the steering system easily and not lost a sense of the road, A mathematical model of Electric Power Steering System was established through Some power research. Study on Control Strategy for EPS, Fuzzy Control and PD to control the parallel control algorithms was introduced.

为了达到对转向系统控制转向轻便又不失路感的目的，通过对汽车电动助力转向系统进行力学分析，建立数学模型，提出一种模糊控制与PD控制并行的控制算法。

Compliance steering operates only at certain lateral acceleration of vehicle. At low lateral acceleration, it doesn't work, the vehicle's performance is like the front wheel steering vehicle's; at high lateral acceleration, it can prevent the vehicle from losing its stability, which is caused by excess steering angle of the rear wheel, by the limiting position function of rubber mounting.

随动转向效应仅在特定的侧向加速度段起作用，在小侧向加速度段，随动转向不起作用，车辆性能与普通前轮转向车一样；而在很高侧向加速度段，它可以通过橡胶悬置的限位作用来确保车辆不致于因后轮转角过大而失稳。

Neutral steer point, NSP –point at which application of a side force will cause no

中性转向点NSP－侧向力不会引起横摆的转向点。

Taken example for solving real engineering problem, the methods and steps for the analysis of the steering-wheel vibration is discussed.

为了解决某型轿车的转向盘振动问题，本文通过对影响转向盘振动的诸多因素逐一进行分析，结合先进的试验手段和CAE分析技术，找出了引发该轿车转向盘振动的主要原因是车轮动平衡质量不合格及固定转向柱管的仪表板横梁刚度不足，通过提高车轮动平衡质量，改进仪表板横梁设计，提高仪表板横梁的刚度和固有振动频率，结合道路试验进行主观评价，改进后的转向盘振动达到了平顺性要求。

In order to improve size selection for shrimps of multi-codends beam trawls fishing in offshore of the East China Sea,experiments of several sea trials for size selectivity of codends with different mesh configuration, including diamond mesh, square mesh and turned through 90° mesh,have been carried out and catch data were collected by comparative fishing method.

选择性模型对哈氏仿对虾和葛氏长臂虾渔获数据的拟合结果显示，选择性模型具有较好的拟合性，但存在航次间差异；不同网目结构网囊的选择性曲线模型都可简化为Logistic曲线；对于哈氏仿对虾，相比菱形网目网囊，方形网目和转向网目网囊的L50较大，而SR较小(菱形和方形网目之间差异显著，菱形和转向网目之间差异不显著)；对于葛氏长臂虾，方形网目和转向网目网囊的L50较大(菱形和方形网目之间差异显著，菱形和转向网目之间差异不显著)。

From this, it follows that driving characteristics of a car cannot be defined as being just over or understeering.

由此，车辆的驾驶特征不能被简单定义为转向过度或是转向不足。

Compared to other models pointed out by foreign scholars, my model was characteristic of multiple periods during evolution of urban systems, complexities of the course of forming urban systems, multiple types of urban functions, periodicity of regional changes of the important regions of urban development, periodicity of dominances of inland central city and seaport gateway city.

此后，随着海疆由开启转为封闭，再由封闭转为开启，最大城市由青岛转为济南，再由济南转为青岛；中心地职能体系由&青岛单中心体系&转换为&青岛、济南双中心体系&，再转换为&青岛单中心体系&；工业发展重点区域也由沿海转向内陆，再由内陆转向沿海；口岸城市的门户职能强度也经历了增强、减弱、增强的不对称&U&型变动；城市体系的空间结构经历了碎化—整合—碎化的过程。

The handgrips glide up and down for steering, somewhat different than today's vehicles where the steering wheel revolves around a steering column.

手柄上下滑动可实现转向，不同于现在的方向盘控制转向。

Because steering axis load of light truck is not very big, so I choose manual steering system for the design, This arragement of steering tapy is also simple and the cost is cheap.

本次中型货车转向系设计由于前轴负荷不太大，故而选择结构简单、制造成本低的机械转向，并使其满足转向系设计的本要求。

If it is not specific to children's reading, true, accurate, lively composition, in particular knowledge and interesting to be highlighted; and young to old people's reading, the image can be canciete towards the abstract, symbolic approach should be adopted as its composition by vivid form Steering in the form of solemn and dignified.

如差老翁成人读物不梢体给笼统、诞妄、不确，构图给平板板滞，格边给不入色常识性和趣味性；差洋不老年到老年人的读物，不梢体可以由具象垂垂转向于笼统，宜拔取象征性伎俩，构图也可由平板板滞的步不天转向于苟且、沉实的步不天。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
