基于统计数据的高速风洞阀门系统可靠性研究

为提高阀门系统的可靠性和故障处理时间,对其进行可靠性研究.通过对不同信息平台得到的高速风洞阀门系统故障数据进行整理统计,以故障发生频率和平均处置时间的乘积构建代价函数,将各类阀门故障按照代价函数值进行排序,根据分析结果,有针对性地采取冗余设计、备件采购、技术改进和制定预案等措施.结果表明:该研究能增加阀门系统的平均无故障工作时间,缩短平均故障处理时间,使可靠性得到有效提升.

Reliability Study of Valve System in High Speed Wind TunnelBased on Statistics Data

For improving valve system reliability and failure disposal time, carry out its reliability research. By sorting out the fault data of valve system in high speed wind tunnel from different information platform, a cost function is established with the product of failure frequency and average disposal time. Different kinds of valve faults are sorted according to the cost function. Measures such as redundancy design, procurement of spare parts, technical improvement and arrangement design can be made based on the analysis results. The results show that the research could be qualified to increase the MTBF of the valve system, shortened the average time for handling the system failure, and effectively enhance the reliability.
