自穩式水翼艇模型阻力試驗規程The effect of reynolds number on rudder hydrodynamic performance is also analyzed. up to the stall angle the computed lift and drag agree well with measurements and other author ' s calculations, whereas stall angle, lift and drag beyond the stall angle are slightly under - predicted. the solver is used to investigate laminar and turbulent separated flows around a 6 : 1 prolate spheroid at high incidence angles and their effects on hydrodynamic forces
應用所開發的求解器,以naca0015翼型舵為算例計算了船舵在不同雷諾武漢理三;大學博士學位論文數下大舵角范圍內的三維粘性流場及水動力,成功地預報了舵的失速角和最大升力,並初步探討了雷諾數對舵水動力的影響;計算結果與現有試驗和計算數據比較,吻合程度相當好,初步檢驗和驗證了該求解器精確模擬粘性流動和計算水動力的能力。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。In this paper, the researching and developing situating at home and abroad on aseismic properties of the masonry structures are reviewed. aiming to the defects of the calculated formulas of the aseismatic shear strength of brick walls in the code for seismic design of building ( gb50011 - 2001 ) and the code for design of masonry structures ( gb50003 - 2001 ), through test on brick wall models between the single wall and the wall with flanges, restoring force characteristics, the behavior at failure of the brick masonry wall and the effect of longitudinal wall under cyclic horizontal loading were analyzed the aseismic capacity has increased by 31 % for wall with flanges, the rigidity and deformation of the wall has gone up greatly too. the conclusion that the effect of longitudinal wall should be comprised in the aseismatic formulas was proposed
本文回顧了國內外關于砌體結構抗震性能的研究與發展現狀,針對建築抗震設計規范( gb50011 - 2001 )和砌體結構設計規范( gb50003 - 2001 )中墻體抗震驗算公式中的不足之處,通過單片墻和帶翼緣墻在垂直荷載和水平反復荷載作用下的對比試驗,研究了帶翼緣墻在水平反復荷載作用下的恢復力特性曲線、磚墻破壞特徵以及縱墻的影響等,翼緣墻的存在,主墻抗剪能力可以提高31 ,剛度及變形能力也均有較大提高的結論,墻體驗算公式中應當考慮縱橫墻共同作用的影響。Experimental data from the towing tank tests show that the hydrofoils give more water - drags on the raft ' s hull, and that the hydrodynamic performance of a ferrying raft will be improved by rational designs of the hydrofoils ' profile, angles of attack as well as the position of hydrofoil on the hull
