Matlab procedure is coded to compute the far - field sound pressure levels of the shell excited by radial point force. the influences of modal truncation, stringers, bulkheads and damping on the shell ' s far - field sound pressure are analyzed, laying down the basis for accurate analysis of the sound radiation from fluid - loaded reinforced double cylindrical shells
本文用matlab編製程序求解了單層殼在徑向激勵力作用下的遠場聲壓級,分析了模態截斷數、縱骨、艙壁板、結構阻尼等因素對殼體遠場輻射聲壓的影響,為準確計算加筋雙層殼在水下振動和聲輻射特性奠定了基礎。Abstract : fatigue cracks in ship hull structures are most likely to occur in the highly stressed structural details. the conventional fatigue analysis is largely dependent on the determination of stress concentration factors ( scfs ) at the locations considered. this paper is concerned with the stress concentration of cutout in transverse web for longitudinal stiffener. a series of finite element models is carried out for the stress analysis of predefined structural details. the tabulated scfs of typical cutouts ( abs tanker rules ) in transverse web for longitudinal stiffeners are presented based on the finite element analysis ( fea ) results
文摘:疲勞裂紋往往發生在船舶結構的局部高應力區,而疲勞分析結果通常取決于任何準確確定結構的應力集中系數.本文研究為鋪設縱骨而在艙壁板上開孔的應力集中,採用有限元方法對預先給定的結構進行應力分析,基於有限元計算結果給出了艙壁板典型開孔(參見abs油船規范)的應力集中系數表According to the fea model of 110, 000dwt oil tank, the distribution of the stresses of the model in more than ten kinds of load cases is calculated. the structural strength of the ship is assessed. the buckling assessment of the main ship plating such as the deck, bottom, side shell, inner shell, longitudinal and transversal bulkhead is undertaken
針對各種規定的計算載荷工況,對該船船體結構進行了強度校核。並對其主要的船體板如甲板、底板、舷側、內殼和縱橫向艙壁板等板格進行了平板屈曲校核。The sound insulation analysis and test methods for double wall of airplane cabin
民機座艙雙壁結構的隔聲分析與隔聲試驗方法The submarine structure is simplified to single or double infinite cylindrical shell stiffened with rings, bulkheads and stringers, focusing on underwater sound radiation from the single shell. the shell motion is described by donnell ' s theory including excitation forces and reactions of rings, bulkheads, stringers and fluid, which leads to the fluid - structure coupling vibration equation. expressing displacements by velocities, applying modal expansion circumferentially and fourier transformation longitudinally result in the shell ' s modal equations of motion
殼體的運動方程採用較為簡單的donnell理論描述,運動方程中包括了激勵力、加筋結構(環肋、艙壁和縱骨)和流場對殼體的作用力,從而組成流場-結構的耦合振動方程,並進一步將方程中的位移用速度表示,然後沿軸線方向進行fourier變換,將速度和各項荷載沿圓周方向進行模態展開,得到了殼體振動的模態運動方程。First divides the protection structure into the bumper and the rear wall, separately study the impact effect of two plates, the recombination is taking together the overall construction research ; secondly, the protection structure took the overall construction, puts the witness plate behind the rear wall, through surveys the real wall and the witness plate damage traces narrates the projectile destructiveness, the form of witness plate are one layer thick plate or multilayered thin plates
一是把防護結構分成防護屏和艙壁兩層單板分別研究其撞擊效應,再結合在一起作為整體結構研究;二是把防護結構作為整體結構,在艙壁後面放觀測板,通過測量艙壁和觀測板的損傷來描述彈丸破壞程度,觀測板的形式分為一層中厚板和多層薄板。And, the coefficient of heat conduction, temperature rise and fall in shelter chamber experiment are made, the result shows the stable plate heat conduction method is applicable, the integration of experience formula for calculation of heat and cool load and experiment analysis is suitable for design and validation of temperature in shelter chamber, the integration can nicely reflect the condition of microclimate temperature in shelter chamber, and have importance reference value for research of microclimate condition in shelter chamber. at last, in article the comparison is made between the felt techniques and foam techniques of the laminate plates, and improved manufacture techniques of composite laminate is brought forward. the experiment indicates the improved techniques can ensure the structure strength and heat preservation and insulation performance
