buffeting load
解釋
抖振負載-
Based measured aerodynamic parameter and simulated wind speed field, time - domain expression of static wind load, buffeting load and self - excited load for bridge and vehicle are introduced
基於測試的氣動參數和模擬的脈動風速場，給出了車輛和橋梁靜風力、抖振力及自激力的時域表達式。 -
Firstly, its natural vibration characteristics are analysised, and the model used for calculating is checked at the same time. then the static analysis under wind load is performed before linear buffeting analysis is done
對該橋首先進行了自振特性分析，並藉此檢驗所建橋梁計算模型的正確性，其次進行靜風響應分析，最後對全橋做線性抖振分析。 -
This paper selects the pulsating wind power density spectrum of davenport and simulates the wind speed time series and the wind load time by matlab. considering the vertical and horizontal correlation of the pulsating wind, the study make use of the time domain analysis of buffeting to carry out the transient dynamic analysis of the whole frame structure which is loaded by the random pulsating wind load. finally, in terms of the whole frame of the pipe belt conveyor, the evaluation for
選取davenport脈動風功率譜，利用matlab模擬脈動風的風速時程曲線和風荷載時程曲線，並考慮脈動風的空間豎向和側向相關性，利用抖振時域法對整體機架結構進行隨機脈動風壓作用下的瞬態動力學分析，最後再對圓管帶式輸送機整體機架結構對環境風荷載的適應性做出評價。 -
