已经采用数字计算法来评估轻型光胎面斜交轮胎在不同速度、充气压力和负荷条件下的温度分布。在用有限元分析进行模拟之前,先分别进行了两组有关评估滞后损失(H)和总应变能(Used)的试验,即动态力学试验和材料试验。滞后损失能量用(H× Used)表示,滞后损失能被认为与生热速率有直接关系。假设温升是由于周期变形而产生的能量消耗所致,则可把这种能量消耗看作是主生热源。滞后能损失被用作将滚动轮胎的应变能密度与热源连接的桥。通过稳态热分析可以获得滚动轮胎的热分布。上述方法表明可以简化滚动轮胎的温度分布模拟。可通过导入有效的计算过程来减少轮胎偶合三维动态滚动模拟的时间。参考其它研究公布的结果讨论了不同条件下的温升。
Numerical calculations have been used to assess the temperature distribution of light-profile bias tire under different speeds, inflation pressures and loads. Before simulating with finite element analysis, two sets of tests were carried out, respectively, on the evaluation of hysteresis loss (H) and total strain energy (In), namely, dynamic mechanical tests and material tests. The hysteresis loss energy is expressed as (H × Used), and the hysteresis loss can be considered as directly related to the rate of heat generation. Assuming that the temperature rise is due to the energy consumption due to the periodic deformation, this energy consumption can be considered as the primary heat source. Hysteresis loss is used as a bridge connecting the strain energy density of a rolling tire to a heat source. The thermal profile of the rolling tire can be obtained by steady-state thermal analysis. The above method shows that it is possible to simplify the simulation of the temperature distribution of the rolling tire. You can reduce the time it takes for a tire to couple a 3D dynamic rolling simulation by importing a valid calculation. The temperature rise under different conditions is discussed with reference to the results published in other studies.
