摩擦

The taper clutch scheme continues to the middle of the twentieth century, when the manufacture, cone-shaped clutch friction relatively simple, easy to repair.

采用锥形离合器的方案一直延续到20世纪20年代中叶，对当时来说，锥形离合器的制造比较简单，摩擦面容易修复。

The amount of force the clutch can hold depends on the friction between the clutch plate and they flywheel, and how much force the spring puts on the pressure plate.

离合器能传递的力的大小取决于离合器盘和飞轮之间的摩擦系数，以及弹簧对压盘的压紧力的大小。

In order to improve the security of the traditional clutch in some working condition and optimize its structure,this article mainly design a new security friction clutch,this type is in the characteristic of brief structure,light weight and little working electricity, and it can be connected with the input shafts of speed-reducer directly.

To enhance the precision of servo systems, friction should be adaptively compensated. With considering the hysteresis in piezo-based micro-feeding components, it is proposed to compensate friction and hysteresis simultaneously in this paper.

根据运动控制发展的需要，本文提出将机械伺服系统中出现的摩擦现象与磁滞现象综合考虑的理念。

Disturbances such as nonlinear friction can be modeled and compensated with reasonable closeness in feed forward, which alleviates the quadrant glitches at the motion reversals.

Disturbances如非线性摩擦进行建模和合理补偿的前馈接近，这缓解了象限故障的议案逆转。

One of these methods is based on self-tuned scaling factors fuzzy controller; the others are based on CMAC. The controllers designed by all these methods have the ability of on-line auto tuning or self-learning, so the under-determined friction could be compensated.

这三种方法都具备在线自调节能力或自学习能力，从而大大减小了系统中出现的不确定性摩擦对系统性能的不利影响。

We analyze the principle of stick-slip motion deeply. From foregoing analysis a result was made that dry friction is the main factor in influencing low speed capability of electro-hydraulic servo system. Dry friction must be compensated for improving the low speed performance. Then a nonlinear model with friction is set up and control methods is discussed.

深入分析了汽轮发电机转速不稳定的原因是由于电液伺服系统在低速区性能不稳定，而影响电液伺服系统低速性能的主要因素是干摩擦，要提高电液伺服系统的低速性能必须对摩擦力进行补偿。

First, the plant and the dynamic model are derived and analyzed. Next, PID controller, adaptive fuzzy controller and adaptive sliding mode controller are established and linear guide produce friction is compensated by Tustin model. From simulation and experiment results, possible implementation, and satisfactory performances, and have been demonstrated.

首先，我们先设计与实现定位系统受控装置并且对其建立与分析系统之动态模型，而后则分别建立PID控制器、适应模糊控制器与适应滑动模式控制器并且对滑轨之摩擦力作补偿设计。

The aim of this design is to alter the conveyor belt, mainly through adding the line friction drive equipment.

摘要本设计是对输送带的改造，主要是通过添加线摩擦驱动装置。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
