中文摘要：

本文结合液压伺服系统的工程实际，运用了L—M方法，对恒压油源系统进行可靠性分析与建模，并给出了系统可靠度的定量评估结果，最后利用该模型对试验模拟数据进行分析，这对工程设计具有重要的指导作用。

英文摘要：

In this paper, the reliability model and the assessment methods were neatly used with com- bining the engineering practice of the Hydraulic Oil System at AGC, and a quantitative assessment result of the reliability system was given. Then the simulation data was analyzed by using the model. This result can guide the engineering design effectively.
