中文拼音 [chuánpōumiànxíng]
船剖面形
英文
ship-like form-
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。With the methods of parametric inputting, interactive inputting and graphic inputting, this system can build the three - dimensional models of ship and modify the model from time to time. moreover, this system can transform the models into ship line drawings that include waterline drawings, transverse section drawings and vertical section drawings
在此基礎上,本文利用參數化輸入、人工互動式輸入和圖形導入等多種方法建立船舶的立體模型,並能實時編輯修改;進一步地,系統能夠由三維模型反演出型線圖,即水線圖、橫剖面圖、縱剖面圖。Solution of nonlinear wave loads in regular oblique seas. based on strip method, thinking about nonlinear factors such as no straight shipboard on waterline, the instantaneous variation of wet surface shape and slamming effect of ship bottom, the numerical methods of nonlinear fluid force in large amplitude oblique regular seas are discussed
關于斜浪規則波中非線性波浪載荷的計算:本文基於切片理論,考慮到船體非直舷、水下剖面形狀的瞬時變化以及砰擊等非線性因素,討論了大波幅斜浪規則波中非線性流體力的時域計算方法。For the specification of the curve surface of ship, this system applies three methods, i. e. triangle, b - spline and nurbs, to express the ship curved surface
