摘要

通过模拟轮胎在平地上滚动，观察其对平面内刚性带振动模式的影响，研究了轮胎的动态特性。采用三种建模方法来理解影响车辆平顺性的轮胎动力学的各种轮胎设计参数。首先，采用简化的三自由度刚性环模型对这些模态进行了基本理解。接下来，使用一个详细的有限元模型来考虑部件顺应性，以研究模式对轮胎开发中使用的最常见设计参数变化的敏感性。最后，为了研究这些轮胎设计在运行中的变化，使用CarSim和FTire模型进行了车辆仿真。相应地调整与轮胎设计参数相对应的轮胎模型参数。观察报告了轮胎设计参数对清晰响应的影响以及有限元和FTire模型之间结果的相关性。

Understanding Tire Dynamic Characteristics for Vehicle Dynamics Ride Using Simulation Methods

The dynamic characteristics of a tire are studied by simulating its rolling over a cleat and observing the effect on in-plane rigid belt vibration modes. Three modeling approaches are used to understand various tire design parameters affecting the tire dynamics relevant for vehicle ride performance. First, a simplified three-degree-of-freedom rigid ring model is used for fundamental understanding of these modes. Next, a detailed finite element model accounting for component compliances is used for studying the sensitivity of the modes to most common design parameter variations employed in tire development. Finally, to study these tire design changes in operation, vehicle simulations using CarSim and FTire models are performed. FTire model parameters corresponding to tire design parameters are adjusted accordingly. Observations are reported of the effects of tire design parameters on cleat responses and on correlation of results between finite element and FTire models.

期刊介绍： Tire Science and Technology is the world"s leading technical journal dedicated to tires. The Editor publishes original contributions that address the development and application of experimental, analytical, or computational science in which the tire figures prominently. Review papers may also be published. The journal aims to assure its readers authoritative, critically reviewed articles and the authors accessibility of their work in the permanent literature. The journal is published quarterly by the Tire Society, Inc., an Ohio not-for-profit corporation whose objective is to increase and disseminate knowledge of the science and technology of tires.
