| 摘 要： | 在汽车工业产品虚拟开发中建立好的轮胎模型是一个瓶颈问题,需要发展直接利用轮胎模态参数对轮胎特性进行全面模拟的高度解析化的模型。该文在初步建立稳态滚动模型和计算方法,以及对垂直特性计入胎侧非线性刚度模型达到高精度的基础上,又引入花纹阻尼,形成轮胎滚动阻力定量模拟模型,得到在80 km/h推荐速度下滚动阻力系数为0.65%。为进一步表明所建模型及模拟方法的成功,将不同半径转鼓上的模拟结果和ISO 18164推荐的转鼓试验结果与转鼓半径的关系做比较,结果具有良好的一致性。轮胎滚动阻力的模拟结果可指导实践,模型及模拟方法可作为动态模拟的重要基础。

| Abstract: | Good tire models are one bottleneck in virtual vehicle development.This study presents a comprehensive analytical model using tire modal parameters.A basic steady rolling model and a precise vertical model are included in a model was that includes tread damping.A rolling resistance coefficient of 0.65% was calculated at 80 km/h.The model was evaluated further by comparison of the simulation results for various drum radii and that recommended in ISO 18164.The results agree well to show that rolling resistance simulations can be used to predict tire energy consumption in dynamic simulations. |
