基于测试数据的装备健康状态评估方法

针对当前装备健康状态评估方法无法反映健康状态变化过程的问题，提出了一种基于测试数据的装备健康状态评估方法。该方法通过对待测部件进行测试，观察测试数据变化规律并对比测试数据的正常范围，分别计算测试部件的基本健康度、健康度变化率和健康度变化幅度，得到了装备动态变化过程中的健康度数学模型，并建立了串联、并联系统的武器装备健康状态评估方法。利用该方法分别对某型潜射导弹发动机、伺服机构液压源的测试数据进行实例分析，结果表明该方法可准确真实反映装备健康状态的变化过程，提供使用者科学有效的故障预测和维修决策依据，更加符合装备基于状态的维修要求，提高了装备完好率和任务完成率，具有较强的可操作性。

Method of Equipment Health State Evaluation Based on Testing Data

Aiming at the problem of current equipment health state evaluation methods can not reflect the changing process, a method of equipment health state evaluation based on testing data was proposed. This method observes the change rule and compares the normal range of test data by testing the equipment, calculate the basic health degree, the changing rate and changing range of health degree, a model of health evaluation in dynamic change process was proposed and a health state evaluation method for equipment of series and parallel system was established. Based on this method, actual measured submarine-launched missile engine and servo mechanism data were used for analysis, the result shows that this method can reflect the real health state during the changing process accurately, provide scientific fault prediction and maintenance decision basis, fit condition based maintenance requirement, improve equipment performance rate and mission capable rate, has a strong operational.
