縱艙壁板 的英文怎麼說
中文拼音 [zōngcāngbìbǎn]
縱艙壁板
英文
longitudinal bulkhead plating-
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。
