基于贝叶斯融合的柴油机性能状态评估方法研究

Research on Diesel Status Evaluation Technology Based on Bayesian Fusion

建立基于贝叶斯融合的柴油机性能状态评估模型,从工程实际出发,对发动机热力参数进行预处理后,确定了先验分布和条件分布计算方法,并应用此模型对飞机发动机的性能状态老化程度进行了评估。

In this paper, the diesel engine performance state evaluating model based on Bayesian fusion is set up. Based on real engineering, after preprocessing the engine thermodynamic parameters, then the calculating method of transcendental distribution and conditional distribution in Bayesian method are determined, and the model is applied to evaluate diesel engine performance state aging degree.
