In the present invention, a method is provided for installing and locating a plurality of sensors distributed on a structure as part of a structural health monitoring system. The method includes verifying the proper installation of the plurality of sensors and determining the location of the plurality of sensors. In one aspect of the present invention, the step of verifying the proper installation further comprises verifying that each of the plurality of sensors are properly coupled to a sensor data collector and verifying that each of the plurality of sensors are installed in a proper location. In another aspect of the present invention, the step of determining the location of the plurality of sensors further comprises determining the positioning of each sensor in reference to fixed structures in the structure.

A method for estimating damage to a structure is provided. The method comprises collecting a plurality of damage estimates over time and filtering the plurality of damage estimates with spatio-temporal filters. The method also comprises generating an enhanced damage estimate based on the filtered damage estimate.
摘要:
A connector including a spacing link, and a first engagement member connected directly or indirectly to the spacing link, and a second engagement member mounted on an extension arm characterised in that the extension arm is mounted with respect to the spacing link so that the extension arm can move from one side of the spacing link to another.

A method for analyzing test data from nondestructive evaluation of an aircraft includes generating a model of the aircraft with an inspection point. The aircraft is mapped to the model of the aircraft. Then, measurement data is generated by nondestructive testing an area of the aircraft corresponding to the inspection point. The measurement data is stored with associated location data of the inspection point and measurement parameters for comparison. The model of the aircraft with the inspection point is displayed. The measurement test data is displayed for a selected inspection position.
摘要:
A transducer for use in a structural health monitoring system comprises a single transducer element. The transducer comprises a transmit assembly coupled to the single transducer element. This assembly is configured to produce a multi-cycle square wave drive signal for stimulating the transducer. Additionally, a transmit/receive switch coupled to the single transducer element is provided. This assembly is configured to isolate the drive signal from the receive assembly used to sense the electrical signal generated from any received elastic waves.
摘要:
A method for determining damage in a structural health monitoring system comprising a plurality of sensors distributed across a structure is disclosed. The method includes decomposing the plurality of sensors into a plurality of sub-arrays. Each sub-array is associated with a current sensor. For each sub-array, data is collected, the data corresponding to electrical signals produced by waves initiated by the current sensor and detected by a receiving sensor. The data is used to calculate a damage measurement for the sub-array. Then, the damage measurement determined for each sub-array is combined to determining an overall damage assessment from the combined damage measurements.
