摘要介绍了一种用于充气轮胎完整热机械分析的新方法，以估计应力和应变的循环变化，并获得轮胎在载荷下滚动的伪稳态温度分布。该方法使用商用有限元代码，并简化了轮胎几何形状的二维表示，以减少计算时间。分析包括三个阶段：充气分析、接触分析和温度分析。为了处理由膨胀和接触载荷引起的大变形，载荷以小增量施加，并且在每个增量中假设线性弹性变形。结构和温度分析可以通过迭代过程耦合，以反映温度变化对材料性能的影响。结果表明，尽管简化的假设，以减少计算时间，有用的近似解决这个复杂的问题C…
Abstract A new approach for the complete thermomechanical analysis of a pneumatic tire to estimate cyclic changes in the stresses and strains and obtain the pseudo‐steady state temperature profile in a tire rolling under a load is described. The approach uses a commercially available finite element code and involves a simplified two‐dimensional representation of the tire geometry to reduce computation time. The analysis includes three stages: inflation analysis, contact analysis, and temperature analysis. To handle the large deformations resulting from the inflation and contact loadings, the load is applied in small increments and a linearly elastic deformation is assumed in each increment. The structural and temperature analyses can be coupled through an iterative process to reflect the effect of temperature changes on material properties. Results obtained indicate that in spite of the simplifying assumptions made to reduce computation time, useful approximations to the solution of this complex problem c...
