摩擦力

Valve running thrust which represents 90% of the travel of the valve stem can be determined by adding stem load and stem packing friction.

阀门运行推力只是阀门阀杆行程力的90%，因此测算阀门推力时，要加上阀杆负载和阀杆填料摩擦力。

The characteristic of system using proportional valve control single rod cylinder is analysed when the cylinder position is in equilibrium.

为了避免非线性摩擦力对控制性能的影响，选用了低摩擦缸为主动缸。

A two-component mixed friction model is used to express the friction force in servo mechanisms.

Built-run organizations to adopt the engineering plastics with Rolling Wheel, friction small, brisk walking, and the structure of small size, will help improve the vertical hook trip.

内置式行走机构采用带滚动轴承的工程塑料滚轮，摩擦力小、行走轻快，且结构尺寸小，有利于提高吊钩的垂直行程。

Reiterate here:The extreme limit of the friction of the tire and ground is a condition, the fixed position angle, that be face by the characteristic, road of the tire to press, hang the characteristic of mourn the system the decision, but don't include the ABS.

在此重申：轮胎与地面摩擦力的极限是由轮胎本身的特性、路面的状况、定位角度、胎压、悬吊系统的特性所决定，但不包括ABS。

Everyone know that make to move the result biggestly is an occurrence before tire lock die moment, if can let the car of system motive has been keep at with the appearance of the tire friction balance, will acquire to make to move the result biggestly so.

大家都知道最大的制动效果是发生在轮胎锁死前的瞬间，如果能够让剎车制动力一直保持在与轮胎摩擦力平衡的状态，那么将获得最大的制动效果。

Because the lock dead of the tire is the result that the car of system friction of motive and tire and ground compare, also be say that the car march forward whether a tire lock die or not of extreme limit is would with the condition that the characteristic, road of the tire face, position the angle, to press, hang the characteristic but" at any time different" of mourn the system.

由于轮胎的锁死是剎车制动力和轮胎与地面的摩擦力比较的结果，也就是说车子行进间轮胎锁死与否的极限是会随轮胎本身的特性、路面的状况、定位角度、胎压、悬吊系统的特性而『随时不同』。

According to the practical characteristics and parameters during hot finishing rolling process of aluminium alloy JP1235, a three-dimensional thermo-mechanical coupled elastic-plastic FEM model was established with the software Marc. And this model was used to simulate the rolling state of F1 stand without back tension. The lateral distribution of rolling force、contact friction force and other mechanic parameters were calculated. Meanwhile, simulated the rolling state considering the influence of mill tilt, and studied the distribution of the mechanics under this state, discussed the effect of mill tile on mechanic parameters and strip steering, which can provide some reference to steering control strategy.

根据JP1235铝合金板带热精轧过程的实际工艺特点和工艺参数，采用非线性有限元软件Marc，建立一个三维热力耦合弹塑性有限元模型，模拟了精轧机组第一机架（F1机架）失去后张力作用后的轧制状态，计算出轧制过程中轧制力、摩擦力等力能参数沿板宽方向上的分布情况，在此基础上，模拟初始轧辊倾斜影响下的轧制状态，并对该轧制状态下的力能参数分布情况进行研究，探讨轧辊倾斜对力能参数分布及跑偏规律的影响，为纠偏控制提供了一定的理论依据。

Low Open and Close Force with Zero leakageValve shaft uses thrust bearings and "O" shaped seal ring to reduce friction, and stuffing box's leakage problem is also solved.

启闭力小，无外漏阀杆采用止推轴承和&O&型圈密封，减少了开关时的摩擦力，解决了填料箱漏水问题。

After it starts, not only adds 35%pressure to edge of shovel, also moves the part weight of front shaft of vehicle to the tail shaft, which can improve 25% frictional resistance.

系统启动后，不但能对雪板的铲刃增加35%的压力，而且还会把车辆前轴的部分载荷转移至后轴，这样可提高25%后轮对地面的摩擦力。

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。
