Topographical thermal imaging for solid square shaft cooling

Abstract

Thermal imaging has its own rapid change and development, both in theory and application. Starting from their military research extended to different real-life applications. This work represents the thermal topographical maps of the thermal image based on the direct projection for material thermal inspection. The test set here uses a square cross-sectional shaft that has been heated to around 200 o C and then measures 9 projections angle of 45o thermal images with an infrared (IR) thermal camera. The final thermal images were analyzed and rearranged to understand the thermal behavior of the shaft with the aid of cooling. The results show that a local slice C_22 indicates twice times in two different projections (2 and 9) with significant differences in temperature with respect to the real measured values. Also, layer C_28 shows the highest temperature difference before about 2.51 o C in projection 4 more than all the other layers. These represent an abnormal behavior for the slices or the local positions mentioned above, which may need more mechanical inspection to confirm the results. The mechanical topographical specifying the projection and slice position will increase the percentage of correctness of local and global assessments for test samples.
