The Monitoring of Machines: Preliminary Study on a Transmission Gear Case

摘要

The application of vibration analysis to the surveillance of the mechanical condition of machines is proposed. A signal processing method, given vibration measurement data, is suggested. This method was validated using a wear test setup for studying the behavior of an automobile transmission to failure. The test bench is described, including type and frequency of measurements as well as measurement methodology. Results demonstrate the feasibility of diagnosing wear on machine parts through the statistical analysis of associated vibration signatures.
