wide-flange beam 中文意思是什麼
wide-flange beam
解釋
寬翼緣梁-
Presented four methods of laser collimation, realized 3 of them with the software of zemax, and meted the requirement of the system design ; 3. realized the laser beam expanding from point - laser to line - laser wide enough to cover the flange trackside ; 4. after image grabbing and processing, picked up the profile of the train wheel
作者獨立完成的工作包括: 1 、提出了曲面測量的光學系統的整體方案; 2 、提出了四種激光擴束的方案,用光學設計軟體zemax完成了其中三種的設計;經過像差分析和追跡,達到了準直擴束的要求; 3 、點光源到線光源的單方向擴展,達到了覆蓋輪緣踏面的要求; 4 、通過實驗採集圖像和圖像處理,提取出被測輪緣的輪廓。 -
In elementary beam bending theory, it is assumed that the stresses are constant through the width of the beam. however, for the wide flange girders, the stresses are not uniform
按照初等梁理論即假定翼緣板具有無限抗剪剛度,寬翼緣箱梁在荷載作用下翼緣的正應力沿著寬度方向上是均勻分佈的。
