Abstract The overall design idea of fault prognostics system for hydraulic components in missile launcher was presented. The monitoring target is determined, and then fault characteristic signal was selected, and finally fault characteristic parameter was abstracted from fault characteristic signal. The system hardware and software platform are respectively DAQ system and LabVIEW 8.0. Fault prognostics for hydraulic components in launcher were carried out by adopting support vector machine.

某型导弹发射装置液压元件故障的预测
阐述某型导弹发射装置液压元件故障预测系统的总体设计思想。确定了监测对象，选取故障特征信号，并从故障特征信号中提取了故障特征参量。介绍了以DAQ系统为硬件平台的系统硬件设计和以LabVIEW8.0为软件开发平台的系统软件设计。应用基于支持向机的故障预测方法实现对发射装置液压元件的故障预测。
