撓鉤 的英文怎麼說
中文拼音 [náogōu]
撓鉤
英文
long-handled hook-
The research shows that : 1 ) the ductility of the hsc bending members constructed is much greater than 5 ; 2 ) increasing the vertical links and distribution steel can increase the deflection under ultimate moment ; 3 ) with appropriate compressive bars, vertical links and distribution steel the increase of moment after yield and the decrease of moment under ultimate moment can be ignored, so the ductility of the hsc bending member is much larger ; 3 ) the width / depth ratio of hsc bending member has no obvious effect on the ultimate compressive strain of concrete ; 4 ) the method used here to calculate the deflection is applicable ; 5 ) the location of crack coincides with the location of vertical links and distribution steel ; 6 ) the bending property of the hsc structure under the blast load can meet the demand of protective engineering
研究表明：本文研究的梁、板構件的延性比遠大於5 ；增加箍筋（鉤筋、分佈筋）含量，可以提高壓區混凝土剝落時的撓度；在適當的受壓筋、箍筋（鉤筋、分佈筋）含量下，可以忽略壓區混凝土剝落瞬間的承載力下降，從而大大提高構件的延性；受彎構件的寬高比對壓區混凝土極限應變的影響不明顯；受彎構件的裂縫間距受箍筋（鉤筋、分佈筋）的布置影響；文中所用的承載力和變形計算方法是可行的。化爆試驗表明，高強混凝土構件的動載抗彎性能能夠滿足防護結構的要求。In the article, it is emphasized on the generally applied adaptive control, sky - hook control and optimum control integrating with the theory and technique of active vibration control on the base of vibration model of vehicle suspension. three performance targets : acceleration of vehicle body, dynamic flexibility of suspension and dynamic load of tyre are evaluated
論文在建立汽車懸架振動模型的基礎上，結合振動主動控制的理論和技術，著重研究了被廣泛應用的自適應控制、空鉤控制和最優控制，並通過計算機進行模擬，對車身加速度、懸架動撓度和輪胎動載荷三個性能指標進行了評價。
