Virtual Age Model for Equipment Aging Plant Based on Operation Environment and Service State

College of Navel Architecture and Power, Naval University of Engineering, Wuhan, 430033, China

摘要: 以等效龄为老化评价指标,建立了考虑使用环境和运行状态的设备老化评价模型——加速寿命模型。研究了连续工作、周期工作状态下设备的使用环境和运行状态对其可靠性及等效龄的影响,分析了等效龄对使用环境、运行状态的敏感性。实例验证表明,该老化评价模型允许对设备寿龄及可靠性相关的重要参数的作用进行量化,得出的结论与实际相符。

Abstract: The accelerated life model based on the operation environment and service state was established by taking the virtual age as the equipment aging indices.The effect of different operation environments and service states on the reliability and virtual age under the continuum operation conditions and cycle operation conditions were analyzed,and the sensitivities of virtual age on operational environments and service states were studied.The results of the example application show that the effect of NPP equipment lifetime and the key parameters related to the reliability can be quantified by this model,and the result is in accordance with the reality.
