波浪弯矩 meaning in English
wave bending moment
Examples
- Then comparative study of bending moments and shearing forces is performed with the results calculated by traditional design loads method for the same assumption and the changes of wave loads are discussed in this paper
在一定假定条件下，将切片法计算的波浪弯矩与剪力同静置法计算结果进行了比较，分析了破损后的载荷变化，为船体总纵剩余强度研究提供依据。 - 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
传统上，船体总纵强度是通过比较许用应力和在名义垂向波浪弯矩作用下甲板或船底上距中和轴最远点的弹性应力来进行评估的。 - Abstract : in this paper , the ship structure is analyzed by using 3d overall structure finite element method and the longitudinal strength is calculated when the hydro - static bending moment , wave bending moment , horizontal bending moment and torsion moment are considered . we compare the calculating result with the one based on the theory of thin - walled box girders and discuss the future of application of the two methods
文摘:本文对3800箱集装箱船进行了整船有限元分析,计算了在设计静水弯矩、波浪弯矩、水平弯矩和扭矩作用下的船体总纵强度,并与基于薄壁梁扭转理论的总纵强度计算结果进行了比较,对两种方法的应用前景作出评论。 - 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。
