At last I calculate the life indexes and fuzzy reliability indexes of side-abrasion failure of rod string failure, and analyze them generally.

再利用模糊可靠性理论计算管杆偏磨失效寿命指标和模糊可靠性指标，最后对其进行综合分析。

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.

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。
