hogging of beam 中文意思是什麼
hogging of beam
解釋
梁的翹曲-
In the hogging condition, double bottom and the side shell remain the ultimate bucking strength, deck and upperwing tank remain the yield stress, and the other parts keep elasticity. then the key to calculate the ultimate strength of ship hull girders is to ascertain the ultimate bucking strength of the stiffened panels. in this regard, the developed formulation is designed to be more sophisticated than previous simplified theoretical method for calculating the ultimate strength of stiffened panels under combined in - plane bending and lateral pressure. fabricatio n - related initial imperfections ( initial deflections and residual stresses ) are included in the panel ultimate strength calculation as parameters of influence. all possible collapse modes involed in collapse of stiffened panels, including overall buckling collapse, column or beam - column type collapse, tripping of stiffeners and local bukling of stiffened web are considered
確定了船體梁整體破壞時的剖面應力分佈之後，關鍵在於確定板架的極限屈曲強度。本文充分考慮了在縱向彎曲、橫向壓力作用下加筋板可能發生的幾種破壞模式，即板架的整體屈曲破壞、樑柱形式的破壞、筋的側傾、腹板的屈曲並同時考慮了初始焊接殘余應力、初撓度的影響，使其更精確的計算加筋板的屈曲強度。對于加筋板中加強筋腹板的局部屈曲，採用解析法推導出筋的腹板的撓度方程及其邊界條件，求解相應的方程，從而計算出腹板的局部屈曲應力。 -
