剖面模数 meaning in English
modulus of section
section modulus
Examples
- Modulus of midship section
舯剖面模数 - Wherethe long bridge deck within 0 . 5 l amidships is regarded as strengthdeck , the midship section modulus and minimum thickness of the deckplating comply with the requirements of 2 . 2 . 1 and 2 . 4 . 2 . l of this ischapter
例1 :在船中部0 . 5l区域内的长桥楼甲板作为强力甲板时,其船中剖面模数及最小厚度应满足本章2 . 2 . 1及2 . 4 . 2 . 1的要求。 - 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。 - 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
研究结果表明:转塔开孔位置在舯前附近对船体总强度影响不大;波浪弯矩极值用概率统计方法估算更为合理;船体结构剖面模数的第一近似值可用波浪弯矩设计极值等来确定。
