基于网络模型的通风系统可靠性分配方法研究

Study on Reliability and it's Distribution technique of Ventilation System Based on Network Model

在系统可靠性设计过程中 ,如何根据具有一定冗余度的通风系统的可靠度进行可靠性指标的分配或再分配 ,是现场通风安全技术管理人员面临的一个课题。以网络工程及可靠性工程理论为指导 ,针对矿井通风系统可修的特点 ,从对系统可靠度和故障率关系的分析入手 ,运用比例组合方法对矿井通风系统可靠性进行再分配 ,并进行了实例说明。

In system reliability design course, the ventilation and safety technology manager at field would face with a subject that is how to carry through the distribution or the redistribution of the reliability guideline being based on reliable degree of ventilation system that possesses the definite redundancy. In this paper, the author takes the network and the reliability engineering theory as the guidance, based on the practice of the ventilation system, starting with the relation's analysis about the system's reliable degree and the failure rate, with the technique of the combination in proportion, has given out the scientific and reasonable reliability distribution technique of to the system, and has made a living example explanation.
