飞机电源系统可靠性预计的计算机分析

The Computer Analysis of the Prediction of Aircraft Electrial Power Supply System Reliability

随着航空技术的迅速发展,对飞机电源系统的可靠性要求越来越高。基于简单系统的可靠性预计方法巳很难满足现代飞机电源系统研究的需要,因此,利用计算机先进复杂系统的可靠性预计研究具有十分重要的意义。 本文根据可靠性理论,分析了飞机电源系统可靠性网络模型的建立;讨论了网络可靠性计算的最小路不交化技术的计算机实现方法及过程,给出了较为详细的计算程序框图。并对一实际的飞机直流电源系统方案的可靠性进行了计算,得到了系统可靠性的变化曲线,为系统的可靠性设计提供了基础。

With the fast development of aviation technique,the requirements of the aircraft electrical power supply system reliability become much higher. In view of this,the reliability prediction method of simple systems can't meet the need of the research on modern aircraft electrical power supply systems. therefore,the reliability prediction of complex systems by computers is very significantIn this paper a network model of aircraf electrical power supply system is analysed according to the reliability theory. The minimal path non-coherent technique and computer realization process are discussed. The program flow——chart is given in detail. The reliability of an example aircraft DC electrical power supply system is calculated. Curves of system reliability are obtained by which the basis for the system reliability design is provided.
