中拱状态 meaning in English
hogging condition
Examples
- 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
当船体梁在中垂或中拱状态下时，假定一个初始曲率，根据各个单元对瞬时弹性中和轴弯矩的贡献，累加得到相对于这个曲率的总弯矩，然后判断弯矩是否达到极值，如未达到，则增加曲率，重复上述过程，直到弯矩为极值为止。 - This thesis used along caldwell ' s direct calculation method of the ultimate strength of ship hull girders , considered the double bottom and upperwing tank to ship ultimate strength contribution , first defined the stress distribution of the whole section of the ship girders . that is : in the sagging condition , deck and side shell of nearby deck remain the ultimate bucking strength , double bottom remain the yield stress . and the other parts keep elasticity
本文沿用caldwell等人直接计算船体极限强度的思想，考虑双层底和顶边水舱对船体极限强度的贡献，首先将船体梁整体破坏时剖面应力分布确定为：在中垂状态下，甲板及甲板附近的舷侧均屈曲，双层底区域则均屈服，其他部分保持弹性状态；在中拱状态下，双层底及之间的底舷侧均屈曲，甲板及顶边水舱区域均屈服，其他部分则保持弹性状态。
