wind-induced motion 中文意思是什麼
wind-induced motion
解釋
風生運動-
Similar cyclic stresses may have occurred due to wind-induced swaying motion during storage.
同樣在存放時由風力引起的橫向擺動也可以產生類似的循環應力。 -
Numerical models are frequently used to simulate water flow in hydraulic engineering. shallow water equations are basic governing equations with assumption of the velocity distribution uniformly in vertical, so they have some limitations on the simulation of some plane flows, such as wind - induced flow, curve river flow and flow nearby the submerged dikes. for above - mentioned reasons, extended shallow water equations are developed by introduction of momentum coefficient, correction of convection and bed resistance in equations of motion
在水利工程中經常需要採用數學模型模擬水流的流態，淺水方程是進行平面流態模擬計算的基本控制方程，但因其忽略了流速垂線分佈的不均勻性，在模擬某些平面流態（如風生流動、河灣水流、潛壩等工程附近的流動）時存在一定的局限性。 -
Wind - induced vibration control of cable by axial support motion
支座軸向運動控制拉索風致振動的研究 -
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。 -
A fuzzy semi - active control algorithm, which uses the feedback of damper motion status, is also presented in wind - induced vibration control of hefei tv tower. the two methods are used respectively and detailed parameter studies are taken in the last method
本文分別計算分析了這兩種控制策略的控制效果，並對后一種控制策略進行了參數分析，最後比較了兩種控制策略的優缺點。
