焊點形態
英文
solder joint geometry-
Then an thorough computer modeling using finite element program with material, geometry and state triple - nonlinear taken into account is carried out on a series of influencing factors, such as comparison with npn - beam splice connection, comparison of varies designed theories, and the varying of fraction coefficient, diameter, grade, pretension and arrangement of bolts, thickness of web and flanges of beam and column, splicing location, axial loading on column, etc. lots of useful conclusions are drawn form computer modelling. finally, design and construction suggestions are given out. this study fills the black in the field of steel beam - to - column connection with cantilever beam high - strength bolted - splicing at both home and abroad
然後，本文在考慮材料、幾何和狀態三重非線性的基礎上，對該連接形式進行了全面的計算機模擬，主要考慮了帶懸臂梁段全螺栓拼接的樑柱連接節點與無拼接的樑柱連接及翼緣對接焊接腹板拼接的連接節點的對比，各種設計方法之間的對比，以及翼緣拼接和腹板拼接的螺栓間距、直徑和數量，拼接點與梁端之間的距離，梁和柱的翼緣、腹板厚度，柱的軸力，接觸面的摩擦系數，翼緣和腹板拼接板的厚度等因素的影響。But there are some technical difficults for the welding of aluminium alloy such as some broken bits being easily found, a large welding distortion can happen easily, hard to distinguish the difference between the solid metal and liquid metal colour, hard to control the temperature, a lot of air holes can be seen in the welding line and so on
但是鋁合金熔化焊時的技術難點在於：焊接時易引起夾渣，焊接變形大，金屬的固態和液態的色澤不容易區別，焊接操作時控制溫度困難，容易產生氣孔等等。如果焊前清理工作不是很好，檢測氣孔往往超標。The distortion resulting from antenna ' s deadweight results that the fact surface departures the theoretical surface regularly. at the same time, because of moulding and weld fault, the measurement data departures the theoretical surface randomly. the process of the data processing is composed of three steps
雷達天線處于架設狀態下，由於自重變形導致實際面形偏離理論面，造成變形系統誤差；而蒙皮表面加工及焊點接觸不良則造成天線面的隨機誤差。At the same time, based on weld pool image characters, a method for image processing is presented, in which gray - scale morphological operators is used to process weld pool images. by this method, the important geometrical parameters of weld pool are measured
同時結合實際的焊接自動化中熔池圖像的特點，詳細介紹如何利用灰度形態學，設計基於com的形態處理運算元，並且實時提取熔池的最大寬度、半長、後部面積、后拖腳等重要的幾何參數。分享友人
