摘要
本文依据可靠性分析理论和实验探讨，采用计算机数字仿真法对NXS型多部位X线机进行系统可靠性研究。该法主要通过FTA故障树计算机建模和仿真，获得了整机可靠性概率分布，MTBF和结构重要度等可靠性指标，并最终对系统可靠性结果进行了详细探讨。
In the paper, according to theoretic reliability analysis and experiment research, the System Reliability of NXS X-ray image medical machine is studied by a new computer digital simulation method. The practicalmethod is mainly suggested on its FTA model simulated by algorithm on a computer, then the Reliabi1ity Probability, MTBF and Structure Importance of the machine are obtained. The System Reliability results are discussedin detail finally.
