In this thesis, an attempt at considering the flexible joint as non-linear torsion spring has been made.

首先，建立了刚性杆非线性关节机器人的动力学模型，之后通过一平面3R机器人进行了数值仿真，说明了在一定情况下，关节的非线性对刚性杆机器人关节变形和末端误差具有重要影响，并在此基础上，讨论了关节线性项、杆的集中质量和关节驱动加速度对机器人关节非线性特性的影响。

Expanded in the toe of the internal weight block size, so that G15 Iron-Wood as the farthest distance from PING far the most forgiving iron and wood.

扩大了位于杆头趾部的内部配重块大小，使G15铁木杆成为PING目前为止距离最远且最具容错性的铁木杆。

In order to solve above problems, a frequency conversion timing unit for screw pump well and an automatic control system were developed.

针对地面驱动螺杆泵抽油杆断、脱频繁及单井提液调整参数难以控制等问题，开发了螺杆泵井的变频调速装置及自动控制系统。

The stability and bifurcation of a thin elastic rod under tension and twist are analyzed, and the results can be applied to determine the stability of a thin helical rod by use of the equivalent stiffness.

分析受拉扭弹性细杆的稳定性和分岔，且利用等效刚度概念将弹性杆的稳定性条件应用于对细长螺旋杆稳定性的判断。

On the pole inscribes the gap,through the switch lever and the signal rod mutual position's change,simulates the rail switch and semaphore's different condition,realizes between the rail switch and semaphore's interconnection.

杆上刻有缺口，通过转辙杆和信号杆相互位置的变化，来模拟道岔和信号机的不同状态，实现道岔和信号机之间的联锁。

With the rotating screw and mesh, these seals in the pump suction space evolving, the suction chamber in which liquid enclosure and along the screw axis from the inhalation of room to move continuously push exhaust side, will be closed in the space been discharged in the liquid, like a nut when the screw rotation continued to move forward is the case, this is the basic principle of the screw pump.

随着螺杆的转动和啮合，这些密封空间在泵的吸入端不断形成，将吸入室中的液体封入其中，并自吸入室沿螺杆轴向连续地推移至排出端，将封闭在各空间中的液体不断排出，犹如一螺母在螺纹回转时被不断向前推进的情形那样，这就是螺杆泵的基本工作原理。

On the basis of analyzing the failure forms of the sucker rod, the existence of the torsional vibration of the sucker rod was approved and its reason was found out.

在综合分析抽油杆破坏形式的基础上，肯定了采油过程中抽油杆扭转振动的客观存在，分析了抽油杆产生扭转振动的原因。

In order to design the rod string and analyze failure mechanism, the dynamics analysis on rod string of surface driving screw pump must be conducted.

地面驱动螺杆泵抽油杆柱动力学分析是杆柱设计、失效机理分析的关键技术。

Partial abrasion of rod string in screw pump well which is surface driven is the main reason that restricts its application, but the prevention method used presently cant solve the problem radically.

地面驱动螺杆泵井抽油杆的偏磨是制约螺杆泵应用的主要原因，目前采用的防治方法不能从根本上解决该问题。

Ball screw known as "free wheeling" ball screw assembly. Ball nut has a ball cage inside which contacts a stop pin on the shaft.

此滚珠丝杆被称作Free wheeling丝杆组件副，螺母内部有一个滚珠隔离圈用来与丝杆两端停止销接触。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
