heal.abstract |
Linear time frequency analysis is employed for event detection in transportation noise signals and condition monitoring of marine diesel engines. Detected events in transportation noise signals are analysed in the time frequency domain and narrow band components of the signal are calculated in order to extract event types. In marine diesel engines shaft torque signals are monitored using the concept of a localised analysis in time and frequency to identify cylinder misfires. Local analysis is performed using a recursive implementation of the short-time Fourier transform. |
