船體相當梁
  • ship : n 1 船；大船；海船；艦〈作陰性看，代名詞用 she her〉。2 三桅船；全裝帆船。3 船形物。4 〈俚語〉賽...
  • girder : n. 【建築】縱梁，大樑，撐柱，撐桿，大型工字梁。 a framed girder構桁。adj. -less
  1. The ship ' s hull is a thin - walled box girder structure composed of stiffened panels. the overall failure of a ship hull girder is normally governed by buckling and plastic collapse of the deck, bottom, or sometimes the side shell stiffened panels. therefore, the analysis of buckling and ultimate strength of ship panels in deck, boltom, and side shells is very important and necessary for the safety assessment of ship structure. in stiffened panels, local buckling and collapse of plating between stiffeners is a basic failure mode, and thus it would also very important to evaluate the buckling and ultimate strength interaction of plate elements under combined loads

    船體梁的總體失效通常取決于甲板、船底板，有時候是舷側加筋板的屈曲和塑性破壞。因此，對于衡量船體結構的安全性而言，對甲板、底板、舷側板進行屈曲和極限強度分析是十分重要且必須的。對于加筋板而言，加強筋間的板格之局部屈曲和失效是最基本的失效模式。
  2. 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。
  3. According to a practical ship structure, three - dimension spatial structure system is established by adopting hybrid girder element and sp panel element

    針對船舶的實際結構，採用雜交梁元和加筋板格元來模擬船舶空間三維結構體系。
  4. For this purpose, a simple method was proposed to simulate the progressive collapse behavior of a ship ' s hull girder subjected to longitudinal bending. in this method the cross section of hull girder is divided into small elements composed of a stififener and attached plating

    傳統上，船體總縱強度是通過比較許用應力和在名義垂向波浪彎矩作用下甲板或船底上距中和軸最遠點的彈性應力來進行評估的。
  5. Study on hull girder strength calculation methods of large naval ship

    大型艦船總縱強度計算方法研究
  6. It shows that the degradation effects of fatigue and corrosion have important influence on the safety of ship structure, especially after the ship has put into service for 10 years. and the detailed inspection should be done at this time to maintain the reliability level of ship hull girder

    計算結果表明：疲勞裂紋和環境腐蝕在船舶服役10年之後對船體梁可靠性有顯著的影響，此時開展詳細的船體結構檢驗對保證船舶營運的安全性具有重要意義。
  7. 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。
  8. For a naval ship with a long strength superstructure and a lot of hatch, it is difficult to evaluate the hull girder ' s strength by general beam theory because of the complexity of the hull structure

    摘要當艦船設有長度較長但開口較多的上層建築時，其船體結構的復雜性使船體總強度很難用常規的梁理論方法確定。
  9. The formulation has been applied to a bulk carrier which sails in the north atlantic ocean. furthermore, the effects of maintenance actions in increasing the reliability level of ship hull girder are analyzed

    由此可見，對存在疲勞和腐蝕損傷的船體梁進行時變可靠性分析時，必須考慮維修因素的影響才能更加符合實際情況。
  10. Firstly, it needs to separate the girder hull into many elements - pulled one and pushed one. secondly, when the ship is in hogging or sagging, you should assume one curvature value so you can get the moment value of every element at this curvature. and then you may add up all the moment of every element

    當船體梁在中垂或中拱狀態下時，假定一個初始曲率，根據各個單元對瞬時彈性中和軸彎矩的貢獻，累加得到相對于這個曲率的總彎矩，然後判斷彎矩是否達到極值，如未達到，則增加曲率，重復上述過程，直到彎矩為極值為止。
