  • System and method for predicting strain power spectral densities of light machine structure
    Patent number: 10890499
    Abstract: A machine includes a frame, an engine supported on the frame, ground-engaging elements supported on the frame and driven by the engine to propel the machine, a machine light structure supported on the frame, a multiple-axis accelerometer positioned to generate an acceleration signal relative to a base of the machine light structure, and a controller. The controller is programmed to receive the acceleration signal, partition the acceleration signal into overlapped window periods, transform the acceleration signal of each overlapped window period into a power spectral density, and pass the power spectral densities of each overlapped window period through a strain power spectral densities prediction model to generate predicted strain power spectral densities of the machine light structure. A health monitor receives the predicted strain power spectral densities and is configured to generate a notification responsive to the predicted strain power spectral densities.
