buckling collapse 中文意思是什麼
buckling collapse
解釋
失穩破壞-
The ship ' s hull is a thin - walled box girder structure composed of stiffened panels. the overall failure of a ship hull girder is normally governed by buckling and plastic collapse of the deck, bottom, or sometimes the side shell stiffened panels. therefore, the analysis of buckling and ultimate strength of ship panels in deck, boltom, and side shells is very important and necessary for the safety assessment of ship structure. in stiffened panels, local buckling and collapse of plating between stiffeners is a basic failure mode, and thus it would also very important to evaluate the buckling and ultimate strength interaction of plate elements under combined loads
船體梁的總體失效通常取決于甲板、船底板，有時候是舷側加筋板的屈曲和塑性破壞。因此，對于衡量船體結構的安全性而言，對甲板、底板、舷側板進行屈曲和極限強度分析是十分重要且必須的。對于加筋板而言，加強筋間的板格之局部屈曲和失效是最基本的失效模式。 -
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。 -
Since the overall failure of a ship hull is normally governed by buckling and plastic collapse of the deck, bottom or sometimes the side shell stiffened panels, it is of crucial importance to accurately calculate the ultimate strength of stiffened panels in deck, bottom and side shell for more advanced structural design of ship structures
由於船體梁的總體破壞通常由甲板、底板或者舷側加筋板的屈曲或塑性破壞控制，因此在船舶結構設計中準確地計算甲板、底板或舷側加筋板的極限強度就顯得尤為重要。 -
The study indicates we must take into account several possible destructive modes such as buckle and yield et al and consider the non - linear effect of post - buckling and post - collapse of components
研究表明，在計算船體總縱強度時，必須考慮構件的屈曲、屈服等各種可能的破壞模式，要考慮受壓構件屈曲后及崩潰后非線性性能影響。 -
Several types of buckling mode and several types of collapse mode for the stiffened panels are mostly analyzed. it is emphasized on the influence of position of loading plane on the ultimate strength of stiffened panels and numerical calculation of stiffener tripping. at last the interaction of ultimate strength for stiffened panels combined different loads is discussed
文中主要分析了加筋板的幾種屈曲模式和幾種失效模式，並著重討論了加載偏心對極限強度的影響和加筋板的側傾強度數值分析，和簡單討論哈爾濱工程大學博士學位論文了組合載荷作用下的加筋板極限強度的相互關系。 -
