该方法将有限元计算与应变检测结合起来,大大提高了有限元计算的精度,对预测套管的挤毁压力、指导高抗挤套管的开发具有一定的参考价值。
With the improvement of the production and manufacture technology of casing, the actual collapse strength of casing cannot be accurately calculated by present API 5C3 formula.
随着套管制造工艺水平的不断提高和制造质量的显著改进,现有的API 5C3公式已不能正确的预测套管实际抗挤抗内压强度。
With finite element method, the collapse strength of casing with ovality and eccentricity under unidirectional uniform and ellipse distributive force was calculated and analyzed.
采用有限元法,计算和分析了壁厚不均与椭圆套管在单向均匀和单向椭圆分布外挤力作用下的强度问题。
Mechanical characteristic of ct is stu***d. The model of bending, internal pressure strength and external collapse strength, diametric growth and stuck-point of ct is established.
研究了连续油管的工作力学特性,建立了连续油管弯曲、抗内压强度和外部挤毁压力、直径增长、纵向伸长及卡点位置分析计算模型。
It is also found that the collapse strength of the even wear model was different from that of the uneven wear one. A quite great error would happen if a wrong model has been used.
同时指出,在计算套管的抗挤毁强度时,用均匀磨损模型代替非均匀磨损模型,计算结果有较大误差。
“Collapse strength”是一个工程或材料科学领域的术语,通常指材料或结构在受压时抵抗塌陷或崩溃的能力。以下从词义拆解和实际应用两方面进行解释:
一、词义拆解
Collapse(倒塌/崩溃):
Strength(强度/抵抗力):
二、实际应用场景 在工程领域,该术语常用于描述:
示例公式: 抗挤强度计算可表示为: $$ P{cr} = frac{2E}{(1- u)} left( frac{t}{D} right) $$ 其中$P{cr}$为临界压力,$E$为弹性模量,$ u$为泊松比,$t$为壁厚,$D$为直径。
注意:具体数值需参考行业标准(如API标准对石油套管的规定)。若需完整技术参数,可查阅提到的有限元分析相关文献。
折叠(collapse)是一个动词,意为突然垮塌或倒塌。例如:
折叠(collapse)也可以作名词,表示失去控制或力量的状态。例如:
崩溃(crash)、倒塌(fall down)、垮掉(crumble)
建立(build)、增强(strengthen)、稳定(stabilize)
力量(strength)是一个名词,指身体或物体的能力、强度或耐力。例如:
力量(strength)也可以指人的精神或道德力量。例如:
能力(ability)、实力(power)、强度(intensity)
弱点(weakness)、无力(powerlessness)、软弱(feebleness)
