模糊可靠性仿真在聚驱井管杆偏磨失效分析中的应用

Application of Fuzzy Reliability Simulation to the Analysis of Side-abrasion Failure of Rod String for Polymer Drive Pump Wells

模糊可靠性课题大多数研究集中在模糊可靠性的解析方法上,而且偏重于元件级的模糊可靠性分析与设计。将计算机数字仿真技术引入聚驱井管杆偏磨失效模糊可靠性分析中,把模糊可靠性的分析范围扩展至机械系统。分析结果误差较小,与现场实际相符。

Fuzzy reliability study mostly focuses on its analytic method, and lays particular stress on fuzzy reliability analysis and design of component. The side-abrasion failure of rod string for polymer drive pump wells is analyzed by using computer simulation method. The extension of fuzzy reliability analysis is expanded to mechanical system. The result of analysis has little error, and accords with fact.
