本船為鋼質全焊接結構淺吃水內河自航沖砂清淤工作船，具單甲板其中艉舵機艙首甲板為升高甲板，單底，橫骨架式結構，方艉及連續上層建築首部採用雪橇式線型。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Firstly, this paper summarizes modern weaponry stealth technology at home and abroad, and lays special emphasis on analyzing stealth problem of cruise missile ’ s guidance head cover, aerocraft radar canopy and other privileged sites. secondly it makes a research on related theories of transparent metallic mesh that applied to missile ’ s guidance head cover and aerocraft radar canopy, and deduces relational expression between transparent metallic mesh structural parameters and radar wave - shielding efficiency, infrared transmitting. we use laser direct writing technique to fabricate a metallic mesh ( dimension : 70mm 70mm ; line width : 5 m ; period : 350 m ) on glass surface, then do experiment to test radar wave - shielding of metallic mesh via radar transmitting and receiving device
本文首先綜述了國內外現代武器系統隱身技術方法;重點對巡航導彈導引頭罩和飛機雷達艙罩等特殊部位的隱身問題進行了研究，研究了金屬網柵用於導彈頭罩和飛機雷達艙罩隱身的相關理論，推導了金屬網柵結構參數對雷達波屏蔽效率和透紅外關系式;用激光直寫工藝，在玻璃表面上製作了一塊面積為70mm 70mm ，線寬為5 m ，線周期為350 m的金屬網柵;在實驗室里用雷達發射和接收裝置測試了網柵對雷達波的屏蔽實驗;認為利用金屬網柵技術對雷達波具有一定的屏蔽作用，而且不影響精確制導的紅外線高效透過。
