| Popis: | 92 In this thesis, optimization techniques combined with finite element simulation of tire manufacturing process are adopted to tackle the inverse design problem of tire die. The process of manufacturing tires includes three steps, which are filling die, curing process and post curing process. Finite element analyses are applied separately to these three steps. In the post curing process, the tire is cooled from cure temperature to room temperature while being held at a constant inflation pressure. Due to the thermal effects and creep of the components materials, the shape of tire will be determined at this step. Accordingly, the study focuses on the process of the post curing inflation, and calculates the ideal die size from the optimized initial tire shape by optimization program. Additionally, designer may obtain much useful information from each analysis of tire forming. A new, efficient design process to estimate die size is developed in this study by the combination of analysis and optimization method. |
