  • Application of smoothing technique for identification analysis of cavity shape in resin structures based on thermal testing data

抄録

<p>In this study, we introduced the smoothing methods into the three-dimensional shape identification analysis based on thermal testing data and compared difference between computational results employing each techniques. Then two models, including smooth shape of an ellipse and other one with a dent, are given as target shape, and time history of the temperature on each target shape is obtained to apply to shape identification analysis. As a result, it is found that appropriate smoothing technique on the shape identification analysis changes according to conditions in target shape. Gaussian filter is effectual in a case where the shape of cavity is identified as including smoother surface from the aspect of performance function. On the other hand, in the case that the cavity surface of the target shape has a dimple, traction method has efficacy for bringing the computational model close to target shape.</p>
