支承

A dynamic model for rotor-stator rubbing system of multilobe bearings which have a combined action of oil-film force, rubbing force and geometrical eccentricity between stator and bearing is put forward in this paper.

本文针对多油叶轴承支承的转定子碰摩系统，建立了当轴承与定子几何不对中时，油膜和碰摩联合作用下的转子系统动力学模型，探寻了该模型的数学求解方法。

The program consists of three modules:(1) Seismic response analysis module, which can compute the effect of multiple-support excitation, nonlinear behavior such as geometrically-non-linear behavior、inelastic behavior and nonlinear connections, nonproportional damping, soil-pile-structure interaction, etc;(2) Seismic resistance check module;(3) Post-processing module.

该程序主要包括三个模块：（1）地震反应分析模块，可以考虑多点激振，非线性（包括几何、材料、支承连接条件的非线性）、非比例阻尼、桩-土-结构相互作用等；（2）抗震能力验算模块；（3）后处理模块。

Finally, the system is investigated experimentally under the theory guidance, and some conclusions, which are useful for engineering, are obtained. The results show that the squeeze film damper is very effective in preventing sub-synchronous and nonsynchronous operation, and the stability of the system can be improved greatly.

最后采用实验研究与数值计算相结合的方法，对挤压油膜阻尼器在滑动轴承支承的转子系统中的减振特性及提高系统运动稳定性的特性进行了深入地分析，并得出了一些对工程应用有意义的结论。

The coating station includes a first coating dispenser pivotally mounted on a first support and at least one exhaust hood.

涂覆台包括枢轴地安装在第一支承体上的第一涂覆布料器和至少一个排气罩。

Practice has proved that the fault mechanics model established is reasonable and provides research basis for polygenetic fault analysis and diagnosis of the device.

通过综合应用我们提出的这两类故障模型，较好地解决了回转支承多源故障的识别与诊断。

Because the rotational characteristic of the device has a certain property of time varying and non-stationary, there is still no satisfactory development that can solve some complicated and polygenetic faults diagnosis produced in the practice.

回转支承装置是许多大型工程设备的关键部件，是正在发展使用中的一种新的结构形式，它联结了设备上部旋转结构和下部固定结构，因此，它的工作状态常常制约了整机的工作状态，对它的故障诊断具有重要的实践意义。

So too large or small cable prestress will exert negative effect on the support structure.

因此，过大或过小的预应力对会支承结构产生不利的影响。

It is used for the crane slewing bearing.

这是用于起重机的回转支承。

At the same time, we can provide the high-quality oil seal, slewing bearings products.

同时，我司可以提供高品质的油封、回转支承产品。

Slewing bearings are basic components widely used in construction machinery industry.

回转支承是工程机械行业的重要基础件。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
