Abstract
In a method for synthesizing fault data for a mechanical system, vibration data is collected from a mechanical system during operation, wherein the vibration data is collected at at least one sensor coupled to the mechanical system. Residual vibration data is synthesized using a mathematical model representing residual forces induced by a particular fault of the mechanical system. The vibration data is combined with the synthesized residual vibration data to generate fault vibration data for the particular fault, wherein the fault vibration data simulates data associated with an unobserved event.
