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。Transitional feature of the arc and metal droplet in the welding process with steam shielded arc is investigated by means of analysing the waveforms of welding voltage and current under different welding regimes and it is found that there are two types of arc process behavor ? " arc starting - arc blowing out - short - circuiting " and " arc - starting - short - circuiting ". under the condition of constant diameter of welding wire and its feeding speed, the arc process behavor can be changed by adjusting the inductance of welding circuit as well as the voltage of power supply. if arc process behaves as alternative process of " arc starting - arc blowing out - short - circuiting " with minimum time duration of arc blowing out and maximum frequency of short - circuit transition, the welding process will be stable with less spatter and smooth weld bead
通過分析不同焊接規范下的焊接電壓和電流的波形.研究了水蒸氣保護下電弧及熔滴過渡的特點，發現其電弧過程行為有「燃弧?熄弧?短路」和「燃弧?短路」兩種形式.在焊絲直徑和送絲速度一定的情況下，通過調節焊接迴路中的電感量和電源電壓，可以改變電弧的過程行為形式.若電弧過程呈「燃弧?熄弧?短路」交替進行，並且熄弧時間最短時，短路過渡頻率最高，在這種情況下，飛濺小，焊道成型好，焊接過程穩定Resistance spot welding in aluminum alloy was tested by ultrasonic immersion method with focusing probe
摘要介紹採用水浸超聲聚焦回波檢測鋁合金電阻點焊焊核直徑。Comparison of c - scan of entire sample and the date of local point a - scan collected and processed with the metallorgaphs of sample cross section showed that the method could be used to determine the spot size of resistance spot welding
對接頭焊點的c掃描及對局部點的a掃描信號的採集與分析，經負際焊點橫截面的金相觀察對比，可以較準確確定點焊的焊核直徑。The constructing technique, of the 160 ? meter diameter welding ball junction double - deck net shell steel structure roofing, of which is in the leading position in china
