| Abstract |
This paper used CT analysis method. Resistance due to life test of silicone rubber socket was analyzed. Silicone rubber sockets with different magnetic forces were manufactured. Lifespan test was conducted on the silicone rubber socket to induce internal structural deterioration. Resistance was measured at each regular life test. CT scan was performed on the silicone rubber socket before and after deterioration. CT analysis method was used based on imaging data. The cause of increased resistance was analyzed. In the CT analysis process of this study, median analysis using Histogram and chain structure connectivity analysis method using Skeleton ROI were applied. Median analysis uses the median and standard deviation of the threshold values ??measured from CT scan results. Median analysis was applied to silicone rubber sockets. As a result of median analysis, an area of ??interest for metal powder with improved X-ray noise was secured. The connectivity of the metal powder was analyzed using Skeleton ROI in the area of ??interest of the metal powder. The increase in resistance of the silicone rubber socket was analyzed using the CT analysis method. As a result of resistance measurement, the silicone rubber socket with high magnetic force measured an improvement of 117.5mΩ in resistance over 70,000 lifespan tests. As a result of the analysis, the higher the magnetic force, the better the metal powder volume and the amount of change in connectivity. The resistance of the silicone rubber socket was compared with the CT analysis results. As a result of resistance and CT analysis, a correlation between the two factors was derived. Resistance rise analysis using CT analysis methods can provide useful data to solve long-term reliability problems of silicone rubber sockets. The CT analysis technique is expected to be able to quantitatively and visually analyze the chain structure and deterioration process of magneto-rheological elastomers with complex structures such as silicone rubber sockets. |
