In this thesis, four types of steel beam - rectangular cfst column connections, including normal welded flange plate ( wfp ) connection, bolted flange plate ( bfp ) connection, stiffened end plate ( sep ) connection and double split - tee plate ( dst ) connection, were designed based on the configuration of steel frame connection. total 8 models, 2 models of each kind of connections were tested under low - reversed cyclic loading at the end of cfst columns. the relationships between force and displacement at the end of columns, the relationships between the moment and rotation of the joints, degradations of strength and stiffness, ductility, failure mechanism and failure characteristics of these four connections under different axial - compression ratios were presented
本文借鑒鋼框架節點構造,設計了四種類型矩形鋼管混凝土柱與鋼梁連接節點,包括常規栓焊( wfp )節點、翼緣全螺栓連接( bfp )節點、雙t板連接( dst )節點以及加勁端板連接( sep )節點,進行了四類節點8個模型試件在柱端低周反復荷載作用下的抗震性能試驗研究,比較了不同軸壓比下節點的滯回性能、強度與剛度退化、延性、破壞機理與破壞特徵,主要結論有: 1 、節點的位移滯回曲線與轉角滯回曲線為塊型分佈,沒有或略有捏攏現象,耗能能力強; 2 、軸壓比對節點滯回曲線有顯著影響,全部節點都有顯著的剛度退化; 3 、位移與轉角骨架曲線在峰值荷載後有較長的水平或下降段,具有良好的延性性能; 4 、從整體抗震性能上看,翼緣全螺栓連接節點、雙t板連接與加勁端板連接節點都優于常規栓焊節點,可在實際工程中加以推廣。Abstract : by means of metallographical examination and sem, the microstructure characteristics, macro - and microfractographs of the brittle broken wheel hull bolt of bj212 automobile have been studied. the results show that the thin - headed screw, with excessively deep carbonitriding layer and hardening layer, has less resistance to brittle fracture in the thin area of its head. at the root of the head connecting the stem, a tensile stress may emerge owing to the non - even quenching stress. those are the two reasons for low torque fracture of bolt
文摘:藉助金相、掃描電鏡等手段對低扭矩脆斷的bj212汽車輪殼螺栓的金相組織特徵,宏觀和微觀斷口形貌等進行了研究,結果表明:這種頭部薄的螺栓,滲層和淬透層過深,使頭部薄區脆斷抗力降低,在頭部與桿的根部,由於淬火應力不均勻導致根部產生拉應力,均是導致螺栓低扭矩斷裂的原因。The modularized and interchangeable accessories reduce not only the variety of accessory, but also the trouble of user, because the same accessory can be applied to mccb with different rated current and the installation can be implemented without bolt just by the particular connective manner. easy range launched by schneider - electric enriched the family of merlin gerin, brought the customers much more variety of choices, consolidated the leader s position of merlin gerin in the area of electric solutions
附件的模塊化設計減少了附件的種類,而通用性則大大減少了使用者的煩惱,同一種附件可適用於多種不同電流規格的塑殼斷路器,電氣附件獨特的卡接安裝方式可以使附件在不需用螺栓連接的情況下可實現快速的裝配。I needed one more bolt to finish the job, but nobody around here had the right type in stock and i had to order one from manchester ? sod ' s law applies again
我再需要一個螺栓就能把活幹完,但周圍沒有一家商店有這種合適的東西,因此我只得向曼徹斯特訂一個事情要多糟有多糟!Our most competitive products contains hex bolt, hex stock set bolt, hex flang bolt, carriage bolt, t bolt, u bolt, machine screw, auto screw, threaded rod, and non - standard fasteners
六角頭螺栓,內六角緊定螺絲,六角頭法蘭面螺栓,馬車螺栓, t型栓, u型栓,汽車螺絲,牙條和特種非標準件等。In practical application, the m10 180 bolts, which are installed in the head cover of the torque divider of ts5560 special automobile, sometimes fracture all of a sudden. according to the tests of acceleration, stress and strain, and the exciting test, it is resonance vibration that leads to the compound - bending fatigue fracture of the bolts. the exciting force caused by drive system, transmitted through the torque divider, produces a 1000 - 1500hz cyclical excitation at the junction of the bolts and head cover, which causes the first order bending resonance vibration of the bolts
通過加速度、應力應變測試實驗和激振試驗的研究,發現ts5560特種車分動器取力器氣缸端蓋m10 180螺栓斷裂問題是由於共振引起的雙向彎曲疲勞斷裂:傳動系統工作所產生的激勵,經過分動器結構的傳遞(特別是分動器一階扭轉模態的放大) ,在螺栓的連接處產生1000 1500hz的振動激勵,其導致螺栓一階彎曲共振,在螺栓一階彎曲模態的阻尼比較小的情況下,使得螺栓產生較大的共振響應,導致螺紋處的彎曲動應力較大,疲勞壽命較低。Our main products : stainless steel bolts, nuts, washers, all rib rods, automotive fasteners and various special fasteners. product main materials : stainless steel, carbon
