然後在上述六種姿態下,得出了加筋板與不加筋板時工作裝置的模態參數,並討論了兩種情況對工作裝置振型與頻率的影響,提出施工操作與結構改進時應注意的一些問題。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。Due to their simplicity in fabrication and excellent strength to weight ratio, stiffened steel panels are also widely used for construction of land based structures such as box girder and plate girder bridges
由於製作簡單且有良好的強度重量比,加筋板也廣泛應用於製造陸基結構物如箱梁和板梁橋等。4. the reliability of ultimate strength of corroded stiffened panels is analyzed

並且船體截面的組成單元(一般是加筋板單元)在達到材料屈服應力之前還可能發生多種形式的屈曲。The author analyses the tripping of stiffener and three patterns of panel ' s invalidation, so to get the curve of stress - strain of panel. this step is the core of the thesis
