船体构件 meaning in Chinese
hull structural member
Examples
- Molded line of metallic hull structure
金属船体构件理论线 - 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，船舶在服役期内要定期接受检验，一旦发现船体构件严重受损，则要对其进行修理。遭受损伤的构件在维修后能恢复其对船体强度的贡献，从而提高船体梁的可靠性水平。 - Abstract : the time - variant reliability analysis of ship hull girders subjected to the deg r adations of fatigue and corrosion is quantitatively carried out in this paper . th e analytical formulations are derived and simple program is compiled . as a case s tudy , the time - variant reliability of a vlcc tank is calculated . it shows that th e degradation effects of fatigue and corrosion are very important for the load - c a pacity calculation of thsip hull girders . after the second special inspection ( 10 years ) , the detailed inspection should be done in order to guarantee the safety of ship navigation
文摘:定量考虑船体构件疲劳裂纹扩展和环境腐蚀对船体梁承载能力的双重衰减因素的影响，对船体梁的时变可靠性进行了分析，列出了时变可靠性分析公式并编制了相应的计算程序.以一艘大型油船的结构可靠性为例，表明疲劳裂纹和环境腐蚀在第二个特检年( 10a )之后对船体梁承载能力有显著的影响，此时开展详细的船体结构检查对保证船舶营运的安全性具有重要的意义 - A time - variant reliability formulation is presented in this paper to account for the effects of fatigue , corrosion and maintenance actions on the first yield reliability of midship section modulus . a probabilistic model for long - term distribution of wave - induced fatigue stress range is established . for the purpose of obtaining the performance of structure that stands random fatigue load , the concept of stress parameter and equivalent stress range are introduced
船舶在由波浪弯矩引起的交变应力作用下，船体构件焊接点处的微小裂纹逐渐扩展；同时，随着船龄的增加，众多结构构件遭受腐蚀的作用；从而使船体梁剖面模数减小，船体梁承载能力衰减，船舶结构的安全性将受到相当大的影响。
