Computer-Assisted Strain-Gage Monitoring and Data Reduction System

摘要

The objective of this program was to design and build a computer-based straingage monitoring system (SGMS) for the Wright-Patterson Air Force Base (WPAFB) using state-of-the-art electronics to assist in real-time monitoring and subsequent reduction and analysis of compressor analog data. During aerodynamic and aeromechanical testing at the WPAFB Compressor Research Facility (CRF), the SGMS monitors blade and vane stress level data provided by sensors attached to a turbine engine compressor. The system monitors vibratory responses, provides ample warning of compressor component failure, and assists test engineers in data analysis. On-line data are presented to the test engineers via a graphics display terminal and printed reports. Keywords: Data reduction, Alarm limits. (Author) (kr)
