In order to make the designation project of the water tunnel rationally in science, qualified in strength and stability and fit other requirements, working safety in the technical environment, furthermore avoiding sympathetic vibration in the working process, the strength and modular analysis is necessarily for the water tunnel models.

而為分析水洞的設(shè)計方案是否科學(xué)合理绿色私人午夜，符合強度、穩(wěn)定性等方面的要求，在工作環(huán)境中是否安全穩(wěn)定国产一级性交高潮片，能否避免工作中產(chǎn)生共振欧美性色视频，對水洞模型進行強度校核和模態(tài)分析是非常必要的。

A good modulation effect could be obtained through this method in comparison with other capacity regulation methods .To be specific, additional energy consumption besides many problems such as compressor sympathetic vibration, refrigerant leakage,ect. can be avoided .So it has a promising application future.

與其它容量調(diào)節(jié)方式相比国产精品自拍网，這種調(diào)節(jié)方式不產(chǎn)生附加能量損失91自啪，并且可以避免變頻壓縮機所存在的共振、密封不良等諸多問題婷婷色五月开心综合先锋影音，可以獲得更好的調(diào)節(jié)效果www777miqi，具有很好的應(yīng)用前景。

Under identical amplitude, when the inherent frequencies equal to the load's frequencies for the structure begin to sympathetic vibration, different point has different displacement which represent under the same frequency ,different point has different values.

在管道結(jié)構(gòu)上不同點123区无码乱伦，相同的固有頻率處對激勵的響應(yīng)值是不同的亚洲不卡无码精品一区二区；在管道結(jié)構(gòu)上的同一點上，不同的固有頻率處對激勵的響應(yīng)值也是不同的男女八x八x视频网站。來源：06c6Aa2BC論文網(wǎng)www.abclunwen.com

Thirdly, theoretical stress analysis of the drum is made, and a finite element stress and model analysis of LW500×1200 basket is made too. The result shows that the drum intension satisfied the demand, and sympathetic vibration will not happen in normal rotate speed. Comparing the real situation, the decanter centrifuge of this type meets the safe demand.

再次国产999国内精品视频免费，介紹了高速離心機轉(zhuǎn)鼓的理論強度計算公式，并應(yīng)用有限元分析軟件ANSYS對LW500 1200離心機轉(zhuǎn)鼓做了有限元強度分析和振動模態(tài)分析182tv免费精品视频，結(jié)果表明離心機轉(zhuǎn)鼓滿足強度要求亚洲国产色图视频，而且在正常轉(zhuǎn)速范圍內(nèi)不會發(fā)生共振現(xiàn)象，對照該型號離心機實際現(xiàn)場應(yīng)用的情況亚洲动漫第18页，本文所研究的鉆井液離心機確實能夠滿足工作安全要求www.九九久久。

It is the gas that drives the exciter and accomplishes sympathetic vibration to make stickup layer break off then achieve the goal of clear for tramcar.
