Table 5.4 shows that for some bending tests the measured values for the ovalisation after unloading (fAB) were lower than the values according to the DNV Offshore Standard OS-F101 [11] formula at maximum bending (fMBS).Part of these differences were the result of Equation (5.15) being a design formula predicting a “safe” value for ovalisation.Moreover,Equation (5.15) predicts ovalisation at maximum bending strain while measurements were performed after the bending test.During unloading of the pipe,a reduction of the ovalisation occurred [29].Ovalisation at maximum bending strain in the small scale reeling tests was not measured.Ovalisation meters measuring ovality during the test were used in the full scale testing,however.
For some bending tests,the measured ovalisation of the pipe,unloaded after the test,was larger than the Offshore Standard OS-F101 [11] prediction for ovalisation at maximum bending strain.This may be due to the DNV Offshore Standard OS-F101 (2000) being valid for pure bending while ovalisation during reeling is the result of bending,a reaction force of the reel on the pipe and axial tension (Figure 5.3 and Figure 5.10).The reaction force of the reel on the pipe in combination with the tension force increase ovalisation during bending [38].It should be realised that ovalisation of the 22mm outer diameter pipes was minimal and difficult to measure.

表5.4表明,小型挠度测试中的卸载后成椭圆形的测量值,低于在根据the DNV Offshore Standard OS-F101 [11]标准的最大弯曲公式中计算出的测量值.(晕…)
Part of these differences were the result of Equation (5.15) being a design formula predicting a “safe” value for ovalisation.
其差值可用等式(5.15)计算得出,该等式用于预测椭圆化的“安全”值.
Moreover,Equation (5.15) predicts ovalisation at maximum bending strain while measurements were performed after the bending test.
此外,等式(5.15)预测了在挠度测试后度量的基于最大弯曲应变的成椭圆形,
During unloading of the pipe,a reduction of the ovalisation occurred [29].
在管道的卸载过程中,成椭圆形缩减.
Ovalisation at maximum bending strain in the small scale reeling tests was not measured.
在小型的卷轴测试中基于最大弯曲应变的成椭圆形是没有规则的.
Ovalisation meters measuring ovality during the test were used in the full scale testing,however.
在该测试中用于测量椭圆度的成椭圆形仪表也可用于大型的测试,但是,
For some bending tests,the measured ovalisation of the pipe,unloaded after the test,was larger than the Offshore Standard OS-F101 [11] prediction for ovalisation at maximum bending strain.
对于某些挠度测试,管道的规则成椭圆形,在测试后卸载,大于…预测基于最大弯曲应变的成椭圆形
This may be due to the DNV Offshore Standard OS-F101 (2000) being valid for pure bending while ovalisation during reeling is the result of bending,a reaction force of the reel on the pipe and axial tension (Figure 5.3 and Figure 5.10).
这可能是因为对于纯挠度…是有效的,…卷轴对管道的反作用力和轴向拉力
The reaction force of the reel on the pipe in combination with the tension force increase ovalisation during bending [38].
在弯曲过程中,卷轴对管道的反作用力和张力增加了成椭圆形.
It should be realised that ovalisation of the 22mm outer diameter pipes was minimal and difficult to measure.
显然,22毫米外径管的成椭圆形是最小的且难以测量.
ps:ovalisation-成椭圆形究竟是个什么东东~
