Abstract

Tire force and moment (F&M) characteristics are important for the analysis and design of vehicle-handling dynamics and ride comfort. Compared with a general tire F&M measuring method, it provides a detailed insight into the generation of tire F&M characteristics by measuring the tire carcass deformation during static and side-slip maneuvers. A tire observation system with two GOM optical measuring facilities was developed to characterize the tire carcass deformation of the standing and rolling tire. Structural parameters of tire carcass flexibility have been identified based on a polynomial physical tire model with the help of measured bending curves of the tire carcass. A good correlation between the measured and estimated tire force and moment has proven the validity of the developed characterization method.

基于光学测量系统的轮胎操纵动力学表征方法的开发

轮胎力和力矩（F&M）特性对于车辆操纵动力学和乘坐舒适性的分析和设计非常重要。与一般的轮胎F&M测量方法相比，该方法通过测量静态和侧滑过程中的轮胎胎体变形，详细了解了轮胎F&M特性的产生。开发了一个带有两个GOM光学测量装置的轮胎观测系统，用于表征直立轮胎和滚动轮胎的胎体变形。基于多项式物理轮胎模型，借助于测量的轮胎胎体弯曲曲线，确定了轮胎胎体柔性的结构参数。测量和估计的轮胎力和力矩之间的良好相关性证明了所开发的表征方法的有效性。
