Abstract

A computer-implemented method for applying passive strain indicators to a component includes creating a plurality of surface curves and a plurality of data points on each of the plurality of surface curves, the plurality of surface curves and the plurality of data points defining the exterior surface of the component. The method further includes receiving data indicative of a user input selection of a selected surface curve of the plurality of surface curves, a selected data point of the plurality of data points on the selected surface curve, and a selected rotation angle. The method further includes determining an output dimension, location, and orientation of a passive strain indicator. The method further includes providing one or more control signals to a passive strain indicator application system to cause the system to apply the passive strain indicator having the output dimension, location, and orientation to the component.

First claim

What is claimed is:

1. A computer-implemented method for applying passive strain indicators to a component, the component comprising an exterior surface, the method comprising:
creating, by one or more computing devices, a plurality of surface curves and a plurality of data points on each of the plurality of surface curves, the plurality of surface curves and the plurality of data points defining the exterior surface of the component;
receiving, by the one or more computing devices, data indicative of a user input selection of a selected surface curve of the plurality of surface curves, a selected data point of the plurality of data points on the selected surface curve, and a selected rotation angle;
determining, by the one or more computing devices and in response to the selected surface curve, selected data point, and selected rotation angle, an output dimension, location, and orientation of a passive strain indicator; and
providing, by the one or more computing devices, one or more control signals to a passive strain indicator application system to cause the system to apply the passive strain indicator having the output dimension, location, and orientation to the component.

2. The method of claim 1 , wherein the determining step is further performed in response to one or more predetermined passive strain indicator characteristics.

3. The method of claim 1 , further comprising performing, by the one or more computing devices, a stress analysis of the component, wherein the stress analysis provides a life-limiting location on the exterior surface.

4. The method of claim 3 , wherein the passive strain indicator is located within the life-limiting location.

5. The method of claim 3 , wherein the selected surface curve extends through the life-limiting location and the selected data point is located within the life-limiting location.

6. The method of claim 3 , wherein the stress analysis is a finite element analysis.

7. The method of claim 1 , wherein the passive strain indicator comprises an analysis region, a locator region, and a serial region.

8. The method of claim 1 , wherein the component is a turbine component.

9. The method of claim 1 , wherein the passive strain indicator is formed from a ceramic.

10. The method of claim 1 , wherein the passive strain indicator application system comprises a robotic arm and a printer.

11. A computer-implemented method for applying passive strain indicators to a component, the component comprising an exterior surface, the method comprising:
performing, by one or more computing devices, a stress analysis of the component, wherein the stress analysis provides a life-limiting location on the exterior surface;
creating, by the one or more computing devices, a plurality of surface curves and a plurality of data points on each of the plurality of surface curves, the plurality of surface curves and the plurality of data points defining the exterior surface of the component;
receiving, by the one or more computing devices, data indicative of a user input selection of a selected surface curve of the plurality of surface curves, a selected data point of the plurality of data points on the selected surface curve, and a selected rotation angle;
determining, by the one or more computing devices and in response to the selected surface curve, selected data point, and selected rotation angle, an output dimension, location, and orientation of a passive strain indicator, wherein the passive strain indicator is located within the life-limiting location; and
providing, by the one or more computing devices, one or more control signals to a passive strain indicator application system to cause the system to apply the passive strain indicator having the output dimension, location, and orientation to the component.

12. The method of claim 11 , wherein the determining step is further performed in response to one or more predetermined passive strain indicator characteristics.

13. The method of claim 11 , wherein the selected surface curve extends through the life-limiting location and the selected data point is located within the life-limiting location.

14. The method of claim 11 , wherein the stress analysis is a finite element analysis.

15. The method of claim 11 , wherein the passive strain indicator comprises an analysis region, a locator region, and a serial region.

16. The method of claim 11 , wherein the component is a turbine component.

17. The method of claim 11 , wherein the passive strain indicator is formed from a ceramic.

18. The method of claim 11 , wherein the passive strain indicator application system comprises a robotic arm and a printer.
