Reliability evaluation of radar power amplification system considering epistemic uncertainty

  • 摘要: 高可靠性部件短时间内很难得到足够的性能数据,致使对部件退化规律的认知存在一定不确定性,无法准确估计系统的可靠性。为实现对系统可靠性准确估计,假定部件性能参数的分布参数为区间变量,建立了基于区间变量的部件性能参数分布模型,给出了部件状态概率的计算方法。对状态性能区间边界进行补偿,定义了区间通用生成函数及其运算法则,提出了考虑认知不确定性的多态系统可靠性评估方法,并对某型雷达功率放大分系统的可靠性进行分析。本文方法克服了性能参数分布信息缺少、无法准确建立状态性能参数分布模型的不足,具有很强的通用性和工程应用价值。
