-
The main results show that : ( 1 ) the mechanism of laser bending is very different from that in bending with hard tools. ( 2 ) the bending angle is varied along scanning direction, and there is a deformation wave in the process. ( 3 ) the effects of sheet length on bending can be neglected while the length is more than 10 times of thickness. ( 4 ) the sheet width has much higher influence on the bending process
分析發現：激光彎曲成形時板料的應力狀態與機械折彎時有根本不同；當激光束沿直線單向掃描時，板料兩端的彎曲角度不同；板料的長度大於10倍板厚或5倍光斑尺寸時，板長對彎曲角度的影響不再顯著；沿掃描方向，距離光斑中心3倍光斑尺寸以外的區域，仍然對彎曲變形量產生影響。 -
From the study results it is showed that turret hole position near the forward of the midship has less effect to the ship girder strength and it is more reasonable using probabilty statistics method to estimate the extreme value of wave bending moment, by which the first approximate value of hull midship section modulus can be determined
研究結果表明：轉塔開孔位置在舯前附近對船體總強度影響不大；波浪彎矩極值用概率統計方法估算更為合理；船體結構剖面模數的第一近似值可用波浪彎矩設計極值等來確定。 -
Abstract : in this paper, the ship structure is analyzed by using 3d overall structure finite element method and the longitudinal strength is calculated when the hydro - static bending moment, wave bending moment, horizontal bending moment and torsion moment are considered. we compare the calculating result with the one based on the theory of thin - walled box girders and discuss the future of application of the two methods
文摘:本文對3800箱集裝箱船進行了整船有限元分析，計算了在設計靜水彎矩、波浪彎矩、水平彎矩和扭矩作用下的船體總縱強度，並與基於薄壁梁扭轉理論的總縱強度計算結果進行了比較，對兩種方法的應用前景作出評論。 -
Then comparative study of bending moments and shearing forces is performed with the results calculated by traditional design loads method for the same assumption and the changes of wave loads are discussed in this paper
在一定假定條件下，將切片法計算的波浪彎矩與剪力同靜置法計算結果進行了比較，分析了破損后的載荷變化，為船體總縱剩餘強度研究提供依據。 -
The ferry - borges load combination method is applied to combine the stochastic processes of stillwater and wave bending moments, and the failure of ship hull girder occurs when the combined value of stillwater and wave bending moments exceeds the first yield bending moment
另一方面，船舶在服役期內要定期接受檢驗，一旦發現船體構件嚴重受損，則要對其進行修理。遭受損傷的構件在維修后能恢復其對船體強度的貢獻，從而提高船體梁的可靠性水平。 -
Through analyzing bending stiffness of composite slabs in the paralled and cross wise wave direction of steel sheet, the author got load - bending stiffness in these two directions. with the finite elements method, the author studied the mechanism and load - carrying characters under uniform loading of composite slabs and put forward a theorem calculating distortion and analyzed crash mode of this structure
通過分別對組合板沿壓型鋼板波紋方向和垂直於壓型鋼板波紋方向彎曲剛度的分析，得出型鋼和壓型鋼板與混凝土組合板兩個方向的抗彎剛度，採用有限元分析方法，研究組合板在均布荷載作用下的工作機理和受力性能，提出撓度計算公式。
