使振动

The efforts that have been made to explain optical phenomena by means of the hypothesis of a medium having the same physical character as an elastic solid body led, in the first instance, to the understanding of a concrete example of a medium which can transmit transverse vibrations ,and at a later stage to the definite conclusion that there is no luminiferous medium having the physical character assumed in the hypothesis.

为了解释光学现象，人们曾试图假定有一种具有与弹性固体相同的物理性质的介质。这种子尝试的结果，最初曾使人们了解到一种能传输横向振动的具有上述假定所以认为的那种物理性质的发光介质。科技文章的另一特点是大量使用复合词与缩略词，复合词从过去的双词组合发展到多词组合；缩略词趋向于任意构词，例如某一篇论文的作者可以就仅在该文中使用的术语组成缩略词，这给翻译工作带来一定的困难。例如

It is shown that because of the high nonlinear of oil film force of SFD, the nonsynchronous response and the bistable operation may occur in the rotor-SFD system, especially the latter with high vibration amplitude, which has a great effect on the reliability of the rotor system.

结果说明了由油膜力的高度非线性所引起的非协调及双稳态，特别是当转子需要频繁的通过双稳态区时，双稳态跳跃将使转子系统的振动迅速增大，在实际应用中应对其引起足够的重视。

Then the flow in the curved pipe and reducing pipe was simulated through using CFD software, know that fluid passing curved pipe, reducing pipe can form secondary flow, vortex shedding, circumfluence, occur separation of boundary layer and periodic circulation flow, make the fluid pulsant, then cause the pipe vibrancy.

然后再应用通用CFD软件对具有弯曲和变径的热风炉管内流场进行模拟，得到当流体流过弯管、文氏管后形成了二次流、环流，并发生边界层分离和周期性旋涡脱落，它们会使后面的管流处于脉动状态，脉动状态的流体在管内流动时，会引起管道系统产生振动。

Based on the theory of force transmissibility ,the model of a vibration isolation system was established through an example.

基于振动力传递率理论，通过实例建立隔振系统的模型，并应用有限元软件对模型进行优化设计，通过对隔振器参数的寻优，使传递至基础的力最小。

The vibration fault of three-phase induction motor makes the equipment run unsafely.

三相异步电动机出现异常振动，使设备运行存在着不安全隐患。

By means of simulink of Matlab, it is known that the method that electric field is strengthened and two damp holes are turned on can lead to transfer ratio of force to be fallen during the phase of low frequency; on the other hand, the method that electric field is weakened and two damp holes are turned off can lead to transfer ratio of force to be fallen during the phase of high frequency.

通过Matlab仿真计算可知，振动物体在低频阶段，加大电场和开启两阻尼孔能使力传递率较低；而在高频时，关闭电场和阻尼孔，其力传递率较小。

This feature authorizes you to select a filter setting which is best suited to your task.
