Systems and methods for environmental testing and evaluation of non-destructive inspection sensors

摘要

A system and method for environmental testing and evaluation of non-destructive inspection (NDI) sensors is provided. The system has a structure having a plurality of NDI sensors to be tested. The system further has an environmental chamber containing heating elements and cooling elements for heating and cooling the NDI sensors when the structure is secured to the environmental chamber. The system further has an impact testing assembly positioned over the structure for impacting the structure. The system further has a data acquisition computer subsystem coupled to the environmental chamber and coupled to the NDI sensors. The data acquisition computer subsystem controls and monitors the heating and cooling elements, and collects and processes temperature and impact data acquired by the NDI sensors.

1. A system for environmental testing and evaluation of non-destructive inspection (NDI) sensors, the system comprising:
a structure having a plurality of non-destructive inspection (NDI) sensors to be tested; an environmental chamber containing one or more heating elements and one or more cooling elements configured for heating and cooling the NDI sensors when the structure is secured to the environmental chamber; an impact testing assembly positioned over the structure and configured for impacting the structure; and, a data acquisition computer subsystem coupled to the environmental chamber and coupled to the NDI sensors, the data acquisition computer subsystem configured to:
control and monitor the one or more heating elements and the one or more cooling elements, andcollect and process temperature and impact data acquired by the NDI sensors to obtain a temperature profile for the structure, to determine one or more installation locations for the NDI sensors on the structure, and to detect a depth and a location of any internal damage to the structure resulting from impact to the structure.
