System and method for predicting strain power spectral densities of light machine structure

A method of generating predicted strain power spectral densities of a machine light structure of a machine, comprising:

• receiving an acceleration signal at a controller onboard the machine, wherein the generate the acceleration signal relative to a base of the machine light structure;
• partitioning the acceleration signal into overlapped window periods;
• transforming the acceleration signal of each overlapped window period into a power spectral density;
• passing 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;
• and
• generating a notification, by a health monitor, responsive to the predicted strain power spectral densities.

A control system for a machine, comprising:

• a controller programmed to:
• receive an acceleration signal at a controller onboard the machine;
• 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;
• and
• a health monitor receiving the predicted strain power spectral densities and configured to generate a notification responsive to the predicted strain power spectral densities.
