中垂状态 meaning in English
sagging condition
Examples
- If not , increase the curvature , and redo the above steps until get the ultimate strength . in the thesis the author analyzes the tripping of stiffened panels by three different methods . based on the above method , the author calculates the ultimate longitudinal strength of a boxlike girder , several ships and many stiffed panels by program
当船体梁在中拱或中垂状态下时，假定一个初始曲率，累积各个单元对瞬时中和轴的弯矩，然后判断弯矩是否达到极限，如未达到，则增加曲率，重复上述过程，直至弯矩为极值。 - 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。
