驰豫铁电体中极化微区动力学分析 - Secondly , introducing the image analyzing technology with reference to the disadvantages of the traditional ferr - graph analysis technology , and with the combination of characteristic parameter optimizing filtration so as to raise a description method of debris micro - morphologic character . thirdly , with the application of mode recognition method , completing the process of debris auto - recognition based on the collected information of the debris configuration characteristics ; and conducting the diagnosis on the aero - engine wear faults according to the theory of particle tribology . fourthly , introducing information fusion technology to solve the problem that a single method can not collect enough fault premonitory information to conduct the wear fault diagnosis , hence to conduct the research and exploration in the field of comprehensive diagnosis on the aero - engine ' s multi - fault premonitory information
本文的研究工作主要包括以下五个部分：首先，介绍航空发动机常见的磨损故障类型，研究磨损故障的失效机理，分析磨粒的产生机理、分类以及形态特征：其次，针对传统铁谱分析技术的缺点，引入图像分析技术，再结合特征参数优化筛选，形成基于图像的磨粒显微形态学特征描述方法：然后，基于提取到的磨粒形态特征信息，应用模式识别方法完成磨粒自动识别，并根据颗粒摩擦学的基本原理进行航空发动机磨损故障的诊断与定位：再后，鉴于单一方法不能提取足够的故障征兆信息进行磨损故障诊断，本文引入信息融合技术，开展航空发动机多故障征兆信息综合诊断方法的研究与探索；最后，基于航空发动机滑油光谱分析与铁谱分析数据，应用时序模型、灰色模型以及组合模型进行磨损故障的预测方法研究。
