基于卡尔曼滤波的热老化性能可靠性预测
Performance Reliability Prediction for Thermal Aging Based on Kalman Filtering
摘要
Abstract
The performance reliability of the nuclear power plant main pipeline that failed due to thermal aging was studied by the performance degradation theory .Firstly , through the data obtained from the accelerated thermal aging experiments ,the degrada‐tion process of the impact strength and fracture toughness of austenitic stainless steel material of the main pipeline was analyzed .The time‐varying performance degradation model based on the state space method was built ,and the performance trends were pre‐dicted by using Kalman filtering .T hen ,the multi‐parameter and real‐time performance reliability prediction model for the main pipeline thermal aging was developed by consid‐ering the correlation between the impact properties and fracture toughness ,and by using the stochastic process theory .T hus ,the thermal aging performance reliability and relia‐bility life of the main pipeline with multi‐parameter were obtained ,which provides the scientific basis for the optimization management of the aging maintenance decision mak‐ing for nuclear power plant main pipelines .关键词
