航空发动机计算机辅助试验技术研究

A STUDY OF COMPUTER AIDED TESTING TECHNIQUE FOR AEROENGINE

本文在论述计算机辅助试验（ＣＡＴ）技术的基础上，结合航空发动机试车ＣＡＴ系统研究，探讨ＣＡＴ技术开发的系统工程方法，介绍数字滤波技术在试验中的应用，通过虚拟仪表技术实现多种信号采集、处理、显示功能。

A system engineering method for development of the Computer Aided Testing (CAT) technique was discussed in the light of a comprehensive review of CAT technique,and investigation of CAT Systems.The application of digital filtering to the Aeroengine Test was also introducted.The focus was put on the achievements of multi-signal acquisition,processing and displaying according to Virtual Instrument conception.The necessity and trend of a man-machine harmonious information environment development with supporting of database system in the aeroengine Test field were considered.
