摘　　要：轮胎翻倾力矩特性对汽车倾翻的研究有重要影响,也是导致轮胎有效侧倾角的主要因素,对轮胎力学特性理论建模有重要意义。从理论及试验两个方面阐明了翻倾力矩的产生机理,推导了轮胎翻倾力矩的理论模型.进行了模型参数的试验辨识,给出了模型计算结果与试验数据的对比曲线。Tire overturning moment (abbreviated as TOM below) is especially important to investigate the vehicle roll-over occurrence and tire effective carcass camber. The causes of TOM generation are first studied from theory and experiment, and then the theoretical model of TOM is developed. Based on the tire test data, the parameters of the model are identified, and the calculated results with TOM model are compared with the experimental results.
