渦流阻尼 的英文怎麼說
中文拼音 [guōliúzǔní]
渦流阻尼
英文
eddy current damping-
As a result, the electromagnetic field intensity is changed accordingly and fluctuating current in the damper coil is created. damping force is mostly produced because of the phase difference between fluctuating current and displacement of rotor. the formulas of fluctuating current and damping coefficient are deduced theoretically, and the calculated results are consistent with the experimental results
通過分析發現電磁阻尼器線圈內由於轉子渦動時變化的磁場而產生的波動電流與轉子位移間的相位差是產生阻尼的主要原因，推導了波動電流、阻尼系數的計算公式，並通過實驗展示了被動式電磁阻尼器的阻尼效應。Study on damp mechanism of eddy acceleration geophone
渦流檢波器阻尼機理研究Using a " vortex intake " device, the underground drainage system has the dual benefit of relieving storm flow in downstream urban areas in districts such as western and kennedy town, and avoiding the difficulty of constructing or enlarging drains and culverts in urban areas and the resultant disruption to traffic that may ensue. the " vortex intake " project is a significant piece of hku s research achievements, and exemplifies the collaboration between academia, industry and government
漩渦進水口的水力工程，不單可以紓緩西區及堅尼地城一帶于暴雨時，因大量急湍的水流往下沖而造成水浸及危險的問題，還避免了在市區興建或擴建排水道及暗渠的工程；在鬧市中進行此類工程十分困難及費時，並且一定會阻礙交通，帶來不便。Stay cable, which is one of the important components in cable - stayed bridges, is susceptible to environmental excitation because of its small weight, large flexible, low damping, then the various vibration is induced, such as vortex - induced vibration, wake galloping, rain vibration, buffeting as well as parametric - induced vibration etc. in this paper, the vibration property of stay cable has firstly been introduced
斜拉索是斜拉橋的重要承力構件，由於拉索自身的質量輕、柔度大、阻尼小，在外界激勵下，易發生各種振動，包括渦激振、尾流馳振、風雨振、抖振以及參數振動等。Stay cables of the long - span cable - stayed bridges are susceptible to vibration under wind loading, or wind incorporated rain excitation, or deck motion due to high flexibility, relatively small mass and very low inherent damping, such as vortex shedding, wake galloping, parameter resonance and wind - rain induced vibration. large - amplitude vibration of cables may reduce the life of cables and threaten safe traffic, and has been considered today as one of the most critical problems for this type of bridge
大跨度斜拉橋拉索具有較小的質量和極低的阻尼，在風、風雨及橋面振動等外部激勵下極易發生振動，如渦激共振、尾流馳振、參數共振和風雨振等，拉索的大幅振動對拉索的使用壽命和橋梁安全運營構成極大威脅，它已成為大跨度斜拉橋急需解決的關鍵問題之一。Finally, the wave equation of the electromagnetic field of this kind damper is derived from the maxwell ' s equation. the magnetic flux density at the boundary is assumed to be harmonic, so the analytical result of the wave equation is solved. when the rotor rotates, eddy currents flowing inside the conducting material field are caused
最後，應用ahrens的電磁軸承簡化模型，從maxwell方程出發推導了應用於本文所述的被動式電磁阻尼器的波動方程，並用傅立葉級數把矩形磁場展開的諧變磁場作為磁場的邊界條件，通過求解波動方程得到磁場的解析解，從而計算了阻尼器對轉子的電磁力和由渦流引起的切向力產生的阻尼器附加功耗。This paper discusses the mechanical damping effect of eddy current, and designs a good experimental demonstration of it
