摘要

摘要: 通过合理假设,建立了机械弹性车轮三维模型和热平衡状态简化传热数学模型,并进行了滚动状态应力、应变分析。根据简化条件,在有限元软件中建立二维稳态温度场模型,仿真得到了滚动状态下胎体内部温度场分布。分析了车速、橡胶材料损耗因子、导热系数和车轮断面宽度对最高温度的影响。应用多元回归技术建立了滚动状态下最高温度与多因素变化回归方程,进行了F分布检验和预测案例的分析,表明所建回归方程可信度很高,可用于预测滚动状态下最高温度。

Abstract: A three-dimensional mechanical model and a heat transfer mathematical model in the thermal equilibrium state were built through reasonable assumptions, and then stress and strain analysis in the rolling state was done. A simplified two-dimensional finite element model of steady-state temperature field was founded in the finite element software, and the steady-state temperature distribution inside the wheel in the rolling state was obtained by simulation calculations. Influences of the speed, loss factor of rubber materials, thermal conductivity and wheel width on the maximum temperature were researched. The regression analysis between the maximum temperature and multi-factors was built, and F distribution test and prediction cases reflect its high reliability, so it can be used to predict the maximum temperature in rolling state.
