装备技术状态动态评估方法

摘要

Equipment technical condition evaluation is the key technique of condition based maintenance.Pointed to multi-parametric condition evaluation,taking the method of Principle Component Analysis to reduce the dimensionality of evaluation index, the paper turns the Multi-Characteristics Evaluation into the Evaluation by Sequential Principle Component.Represent the equipment technique state by a dimensional vector,which contains equipment technical condition deterioration degree,condition deterioration tendency and condition deterioration rate,and verify the model by an example.%装备技术状态评估是状态维修中的关键技术,针对多参数下的状态评估问题,采取主成分分析方法对评价指标做降维处理,利用有序主成分进行评估,用装备技术状态劣化度,状态劣化趋势和状态劣化速率组成的向量表示装备的技术状态,通过实例验证模型的有效性.
