deflection velocity 中文意思是什麼
-
According to the theory analysis and engineering practice, the application of natural vibration features in bridge inspection is introduced. during the transient dynamic analysis of pubugou cfst arch bridge, the time history responses of the structure under uniform velocity moving load and impact load are analyzed, and the amplification coefficients of deflection and internal forces of the structure are intensively analyzed
在瀑布溝大橋的瞬態動力分析中，模擬分析了當移動荷載以不同速度通過橋面時的時間歷程動力響應以及在沖擊荷載作用下橋跨結構的時間歷程動力響應，並對橋跨結構在移動荷載和沖擊荷載作用下的動力放大系數作了較為詳細的分析。 -
From the results, we can see that jinhuai bridge has no noticeable vertical deflection peak. it is mainly because of the restrictions of some parameters such as velocity of the vehicle on highway and damping of the bridge, which can limit the peak values
計算結果表明，公路橋梁也存在多個瞬態響應相互疊加的問題，但由於受車輛行駛速度和阻尼因素的影響，津淮剛架拱橋沒有出現明顯的共振峰值。 -
4. it is shown from the dynamic test results that the effects are different at the different places with the same load, the impact changes with the different velocity of the truck, which affects the deflection of the bridge. 5
4 、從此次動載試驗結果可以看出，同一荷載橫向布置不同，對橋梁結構的動力影響不同，不同車速對橋梁沖擊作用不同，會使橋梁結構的動撓度發生變化。
