本信息报告介绍了SAE推荐规程J1106《乘用车轮胎稳态力和力矩特性测量实验室试验机和程序》的背景和基本原理。SAE J1106的目的是定义设备设计和测试程序的标准，以便可以直接比较来自不同实验室的数据。尽管这种标准化不是与轮胎开发相关的测试的要求，但在车辆设计和轮胎选择问题的背景下是必要的。 开发SAE J1106采用的基本方法是整合和记录现有技术，体现在目前用于常规轮胎评估的设备和程序中。目前使用仅限于研究应用的设备和程序未被考虑。然而，在本信息报告中讨论了研究经验，以提供SAE J1106的背景和依据。因此，材料包括速度效应、污染物动态测试、牵引力、表面几何形状和SAE J1106中未考虑的其他主题。为了预测SAE J1106提出的问题，扩大了范围。

This Information Report presents background and rationale for SAE Recommended Practice J1106, Laboratory Testing Machine and Procedures for Measuring the Steady Force and Moment Properties of Passenger Car Tires. The purpose of SAE J1106 is to define standards for equipment design and test procedures so that data from different laboratories can be directly compared. Whereas such standardization is not a requirement for testing associated with tire development, it is necessary in the context of vehicle design and tire selection problems. The basic approach employed in developing SAE J1106 was to consolidate and document existing technology as embodied in equipment and procedures currently employed for routine tire evaluations. Equipment and procedures whose current use is restricted to research applications were not considered. Research experience is discussed in this Information Report, however, to the extent deemed necessary to provide background and rationale for SAE J1106. Material is therefore included on speed effects, contaminants dynamic testing, traction, surface geometry, and other subjects not considered in SAE J1106. The scope was expanded in an effort to anticipate questions raised by SAE J1106.
