本信息报告介绍了sAE推荐规程J1106、实验室试验机和测量乘用车轮胎稳态力和力矩特性的程序的背景和原理。然而，本信息报告讨论了研究经验，以提供推荐实践的背景和理由。因此，材料包括速度效应、污染物、动态测试、牵引力、表面几何形状和推荐实践中未考虑的其他主题。本报告首先对影响轮胎力和力矩的因素进行了一般性讨论，并对相关研究和测试活动进行了简要的历史回顾。作为车辆设计的主要考虑因素，他们提出了轮胎和力矩的设计要求。 从总体系统结构到特定子系统需求，对影响试验机选择和设计的因素进行了广泛的审查。详细讨论了测试方法、数据处理、测试结果的表示和解释。本报告最后讨论了“特殊试验”的设备和程序，这些试验目前不是例行进行的，但为车辆设计师提供了重要且越来越感兴趣的数据。

This information report presents background and rationale for sAE recommended Practice J1106, Laboratory Testing Machine and procedures for measuring the Steady State Force and Moment Properties of passenger Car tires. Research experience is discussed in this information report, however, to the extent deemed necessary to provide background and rationale for the Recommended Practice. Material is therefore included on speed effects, contaminants, dynamic testing, traction, surface geometry, and other subjects not considered in the Recommended practice. the report begins with a general discussion of the factors affecting tire forces and moments, and a brief historical review of associated research and testing activities. A discussion is presented of the principal requirements for tire force and moment data as they derive from considerations of vehicle dynamics and tire design. Factors affecting test machine selection and design are reviewed in a broad context ranging from overall system structure to specific subsystem requirements. Methods for testing, data processing, and presentation and interpretation of test results are discussed in detail. The report concludes with a discussion of equipment and procedures for "special tests", not currently performed on a routine basis, but which provide data of significant and growing interest to the vehicle designer.
