Abstract

This study investigates a sensor calibration method for accurately measuring the three-axis contact forces of a single tread block using sensor-equipped tires. Two calibration methods were examined: a static method based on forces generated by applying three-axis displacements, and a dynamic method using rolling contact. Significant errors were observed in the static method when road surface sensors were used as reference values during tire rotation. In contrast, the dynamic method showed minimal speed dependency but was influenced by the slip angle and inflation pressure. It was confirmed that the accurate reproduction of three-axis contact forces from tire sensors is possible if calibration coefficients corresponding to the slip angle and inflation pressure are available. Several methods have been proposed previously to measure the contact force of the entire tire by attaching sensors inside the tire; however, the method proposed in this study can measure the triaxial load acting on a single tread block, which is particularly useful for designing the tread pattern in the contact patch and is unique from previous studies. Considering the conditions commonly used in general tire tests, it will be necessary in the future to establish calibration coefficients that consider the slip angle, tire inflation pressure, and speed; in addition, the validity of linear interpolation should be examined.

在滚动接触条件下安装在胎面块上的力传感器的校准

本文研究了一种传感器校准方法，用于精确测量单个胎面块的三轴接触力。研究了两种校准方法：基于施加三轴位移产生的力的静态方法和基于滚动接触的动态方法。在轮胎转动过程中，以路面传感器作为参考值，静态方法误差较大。相比之下，动态方法显示出最小的速度依赖性，但受滑移角和充气压力的影响。结果表明，如果有对应于滑移角和充气压力的校正系数，则可以准确地再现轮胎传感器的三轴接触力。以前已经提出了几种方法，通过在轮胎内部附加传感器来测量整个轮胎的接触力；然而，本研究中提出的方法可以测量作用在单个胎面块上的三轴载荷，这对于设计接触片中的胎面图案特别有用，并且与以往的研究相比是独一无二的。考虑到一般轮胎试验中常用的条件，将来有必要建立考虑滑移角、轮胎充气压力和速度的校准系数；此外，还需要对线性插值的有效性进行检验。

期刊介绍： Polymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of applications and industrial products as well as nanoscale characterization. The scope includes but is not limited to the following main topics: Novel testing methods and Chemical analysis • mechanical, thermal, electrical, chemical, imaging, spectroscopy, scattering and rheology Physical properties and behaviour of novel polymer systems • nanoscale properties, morphology, transport properties Degradation and recycling of polymeric materials when combined with novel testing or characterization methods • degradation, biodegradation, ageing and fire retardancy Modelling and Simulation work will be only considered when it is linked to new or previously published experimental results.
