摘要
为了提高游梁式抽油机结构的可靠性 ,采用蒙特卡罗法和随机有限元方法对其结构可靠度进行了数值模拟。该数值模拟算法在解决可靠度问题时高效、实用 ,对于解决大型复杂结构的可靠性问题优势尤为明显 ,同时表明基于随机有限元的抽油机可靠度分析可以全面地考虑各种因素的不确定性 ,使评定模型更加合理 ,更加符合工程实际 ,也便于工程应用。
To improve the structural reliability of beam pumping unit, numerical simulation of the structural reliability of the unit is made by means of Monte-Carlo method and response surface method. The result shows that the beam pumping unit can be designed more reliably and reasonably with the method since undetermined factors are considered comprehensively.
