Development of the Internal Tube Material Properties for a Self-Inflating Tire


Article Preview

In this study, the tube material for Self-Inflating Tire was synthesized. A few suitable materials for the tube material compounding process were identified through a literature review. Using the material properties of this tube, CAE modeling was done for analysis. The ANSYS Fluid Structure Interaction (FSI) method was then used to consider the internal flow with the structure. In addition, a machine was prepared for testing the performance of the tube. The results of the CAE analysis were compared with results of the testing machine. The developed equipment and systems can be used for the manufacture of high-performance and safe tires. Finally, the prototype of the tube was prepared and fitted in a tire, and the driving performance of the vehicle tested. Using this test result, compatibility of the tube's material has been confirmed.
