與單向犁相比，其優點在於：耕地無開、閉壟，地表平整，降低了耕后整地的能量消耗，減少了地頭的空行程，因而大大提高班次生產率。為了滿足犁體梭式作業的要求，我們採用了一隻小容積雙作用的液壓油缸；同時對犁壁曲面的形狀採用了近似圓柱形的對稱設計。但經過一段時間的田間試驗，我們發現：該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中磨損較為嚴重；主犁梁和油缸缸體的連接部分（即油缸底座）突然發生了斷裂，造成整個犁體無法正常工作。The equations of motion governing the axisymmetric elastic deformation of finite orthotropic cylindrical shells, involving the effect of transverse shear and rotational inertia, are derived. by applying the reverberation method, the displacement and the resultant forces of the shell in the phase space are expressed. then the transient waves in the finite orthotropic cylindrical shell subjected to the axisymmetric impact are obtained by using inverse laplace transforms. furthermore, the transient solutions are decomposed to the generalized ray integrals and computed numerically
分析了計及剪切變形和轉動慣性的有限長正交異性圓柱殼中彈性瞬態波的傳播問題，採用回傳矩陣法，在相空間中給出了位移和內力的表達式。再利用laplace逆變換，得到正交異性圓柱殼受軸對稱沖擊作用時彈性瞬態波解，然後將其分解為若干廣義射線積分之和，並用數值方法求解之。A design method of symmetrical reinforcement members subjected to small eccentric compression by secant method
矩形截面對稱配筋偏壓柱由軸壓承載力控制配筋時的鑒別條件Yingxian wooden pagoda has favorable aseismatic capability, as it used similar modern core - in - core structure, and fixed many batter brace make it become modern rigid reinforced floors in every hidden floor, and slope of bearing post made it that the level and uprightness frame integrate tightly. under the deadweight, every structural floors form centripetal force. those earthquake resistant measures resist many the strong destroy of earthquake in history
由於木塔採用了唐代殿堂內、外分槽的結構形式，用兩層柱圈構成筒體，並逐層加設了層高較低稱為平坐的剛度加強層，再加上兩圈柱子都由下至上向內傾斜對筒體形成環箍力，這些措施幫助木塔抵抗了多次強烈地震而未倒。2 the effects of load angle on load - bearing capacity of l, t and + - shaped columns under axial compression and biaxial bending are discussed. as for l and t - shaped columns, load angle has a great effect on bending capacity of them, mainly because of the asymmetry of sections. but for + - shaped columns, the effect of load angle on load - baring capacity is not much significant
2討論了荷載角對l 、 t和十形柱受彎承載力的影響，表明l 、 t形柱由於截面不對稱，縱筋分佈不對稱，造成某一荷載角下承載力較大，而另一荷載角下承載力又很低。In this paper, the high - temperature low - cycle fatigue life and fatigue crack propagation life tests are carried on the cylindrical axial symmetry specimens having precrack or non - precrack with different types of notches of 16mnr steel in common use in the petrochemical industry contacting coke drum equipment, the stress / strain and the range of stress / strain of dangerous points are received through stress analysis of the specimens using finite element program under multi - axial stress state. at last, the equations of evaluating the high - temperature low - cycle fatigue life and the fatigue crack propagation life are found through using the least - square regression method
本文採用無預裂紋和帶預裂紋環狀缺口圓柱形試樣，進行了石化焦炭塔設備常用材料16mnr多維應力狀態下不同缺口形式的高溫低周疲勞總壽命試驗及裂紋擴展壽命試驗，並利用有限元程序對試樣缺口周圍及裂紋尖端附近進行了軸對稱多維應力狀態下的應力、應變場分析，來評價材料不同條件下的高溫低周疲勞總壽命和裂紋擴展壽命，最後利用最小二乘回歸方法，得到了該材料高溫低周疲勞總壽命和裂紋擴展壽命評價方程。Computation of symmetrical reinforcement for rectangular cross sectional bi - eccentrically compression reinforced concrete column
矩形截面雙向偏心受壓鋼筋混凝土柱對稱配筋計算The results of the limited element analysis and experiment study confirms that both the resisting ended batten and using angle batten in place of plate one could make the laterally stiffness of such member more strong. that maybe provides somewhat practical benefits for designing the twin - wall truss
本文還通過矩陣分析法和模擬試驗研究，證實了端綴板的存在對抵抗側向屈曲有明顯提高；而選用角鋼代替綴板材料相對于板形板，有助於提高構件的側移剛度和翹扭轉剛度，這對于單軸對稱綴板柱的設計也具有一定的實用價值。By the use of dynamic buckling supplementary restraint conditions at the compression wave front of cylindrical shells at the instant when the buckling occurs, the critical load and dynamic buckling modes of shells were calculated from the solutions of finite element characteristic equations
計算結果揭示了圓柱殼彈性軸對稱動力屈曲變形發展的機理，以及軸向應力波和屈曲變形的相互作用規律。This fine oriental complex adopts a symmetrical design with its buildings sprawling along a central axis, complete with colonnades, two wings and a tower at the apex. the three gorges of the yangzi river
