摘要
射电望远镜的可靠性问题广泛存在于射电望远镜设计、制造、正常工作等整个全寿命周期,对其子系统进行可靠性评估与可靠性指标分配是射电望远镜设计阶段的关键步骤。文中从射电望远镜的可靠性评估与可靠性指标分配出发,提出了一种基于粒子群优化层次分析的模糊综合评价模型,并基于此模型从多指标综合模糊评价角度对射电望远镜的子系统进行了可靠性评估与可靠性指标分配。可靠性评估分配结果表明射电望远镜子系统中可靠性评估最低的是主反射面系统,需要根据评估结果分配较高的可靠性指标并针对性地提高其可靠性以提高系统的整体可靠性。
The reliability problem of radio telescopes widely exists in the whole life cycle of radio telescopes,such as the design,manufacturing and normal operation of radio telescopes.The reliability evaluation and reliability index allocation of its subsystems are the key steps at the design stage of radio telescopes.Based on the reliability evaluation and reliability index distribution of radio telescope,a fuzzy comprehensive evaluation model based on particle swarm optimization analysis is proposed in this paper.Based on this model,the reliability evaluation and reliability index distribution of radio telescope subsystem are carried out from the perspective of multi index comprehensive fuzzy evaluation.The results of reliability evaluation and allocation show that the main reflector system has the lowest reliability evaluation in the radio telescope mirror system.It is necessary to allocate higher reliability indexes according to the evaluation results and improve its reliability to improve the overall reliability of the system.
