    摘要: A method and method of estimating fatigue life of a structure is disclosed. In one embodiment, the method may include determining strain on the structure using a plurality of gauges positioned on the structure. The method may also include detecting a parameter of the structure with a plurality of sensors positioned on the structure. Further, the method includes converting the detected parameter and the determined strain to proportional loads acting on the structure and transforming the proportional loads to coordinate system data associated with the structure. Based on the coordinate system data, the fatigue life of the structure may be estimated.

    摘要: Systems and Methods are disclosed for the detection and imaging of ultrasonic energy. Embodiments of the invention utilize an array of ultrasonic sensors where data from each of the sensors are processed by RMS-to-DC conversion. In addition, embodiments of the invention output a contour map based on detected ultrasonic energy and blend at least one feature of the contour map with a feature of a visible image so that a blended image can be displayed to an operator. Furthermore, embodiments of the invention provide a system and method for repositioning an array of ultrasonic sensors with respect to target area or Unit Under Test (UUT) to facilitate a thorough and repeatable test.
