22FTM19. Implementation of a Gear Health Monitoring System on a Power Recirculating Test Rig Using the Average Log Ratio (ALR) Algorithm
The ability to detect the onset of a gear system failure via accelerometer measurements is of interest in a research environment as well as in gear systems deployed in the field. An accelerometer based gear health monitoring system is described which was developed for use in a laboratory setting for monitoring power recirculating gear tests. Even angle resampling, time synchronous averaging (TSA), and average log ratio (ALR) algorithms are utilized to detect the onset of gear damage. A summary of these signal processing concepts is given, along with an overview of system hardware, signal processing workflow, and sample data.
