Abstract
Methods and systems are provided for obtaining structural health data for evaluating a structural health of a component. A transducer detects a first signal representative of a signal transmitted through at least a portion of the component. An estimated signal for a remote transducer is determined based on at least the first signal and a transfer function.
Claims15
A method for obtaining structural health data for evaluating a structural health of a component, said method comprising:
- detecting, at a transducer, a first signal representative of a signal transmitted through at least a portion of the component;
- determining whether the first signal has a signal-to-noise ratio below a predetermined threshold;
- scaling, at a computing device, the signal transmitted through at least the portion of the component if the signal-to-noise ratio is below the predetermined threshold such that the signal-to-noise ratio is scaled to be above the predetermined threshold;
- and
- determining, at the computing device, an estimated signal for a remote transducer based on at least the first signal and a predetermined transfer function representative of a relationship between the transducer and the remote transducer.
An array of transducers for use in obtaining structural health data for evaluating a structural health of a component, said array comprising:
- a first transducer configured to transmit a signal through at least a portion of the component and scale the signal such that a signal-to-noise ratio of the first signal is above a predetermined threshold;
- a second transducer configured to detect a first signal representative of the signal transmitted through at least the portion of the component;
- and
- a third transducer in a predetermined position such that a computing system is configured to determine an estimated signal for the third transducer based on at least the first signal and a predetermined transfer function representative of a relationship between the second transducer and the third transducer.
A structural health monitoring system for use in obtaining structural health data for evaluating a structural health of a component, said system comprising:
- a first transducer configured to transmit a signal through at least a portion of the component;
- a second transducer configured to detect a first signal representative of the signal transmitted through at least the portion of the component;
- a computing system programmed to determine whether the first signal has a signal-to-noise ratio below a predetermined threshold, scale the signal transmitted through at least the portion of the component if the signal-to-noise ratio is below the predetermined threshold such that the signal-to-noise ratio is scaled to be above the predetermined threshold, and determine an estimated signal for a remote transducer based on at least the first signal and a predetermined transfer function representative of a relationship between the second transducer and the remote transducer.
