Abstract

This article is devoted to the research of the interaction of the wheel of a GAZ light commercial vehicle with a hard supporting surface. The relevance of this problem is due to the need to adequately reproduce the force reactions acting on the tire in the contact patch, when modelling the vehicle dynamics. High similarity of the real process and its modelling are guaranteed if there is a significant empirical data set for a particular tire model, which can be ensured only by the results of field tests. Specialists from Nizhniy Novgorod State Technical University have developed a schematic diagram of a road measuring unit, a test methodology and built testing unit as well as conducted full-scale tests. The experiment was conducted in the auto racing track at an ambient air temperature of 20 °C on a dry road asphalt surface with a high friction coefficient (0.4 – 0.8). The resulting array of experimental data was processed and presented in numerical trigonometric polynomials form (PAC 2002). The table comparing theoretical and experimental values presented in the results of this article confirms the high level of convergence. The maximum discrepancy in absolute value does not exceed 5%.

轻型商用车轮胎pacejka模型参数辨识及动力学研究

本文对GAZ轻型商用车车轮与硬支承面的相互作用进行了研究。这个问题的相关性是由于在对车辆动力学建模时，需要充分再现作用于轮胎接触片的力反应。如果存在特定轮胎模型的重要经验数据集，则可以保证实际过程及其建模的高度相似性，而这只能通过现场测试结果来保证。下诺夫哥罗德国立技术大学的专家制定了道路测量装置的示意图、测试方法和建造的测试装置，并进行了全面测试。实验在环境空气温度为20℃的赛车跑道上，在高摩擦系数(0.4 ~ 0.8)的干路沥青路面上进行。所得到的实验数据阵列被处理并以数值三角多项式形式呈现(PAC 2002)。本文结果中给出的理论值和实验值对照表证实了高收敛性。绝对值最大差异不超过5%。
