车辆乘客的舒适性和疲劳是主要的工程考虑因素。其中涉及的许多因素包括振动和听觉障碍。除车辆的其他部件外，轮胎还参与了激振和噪声。此外，轮胎也可能产生导致车辆横向漂移的力。本SAE推荐实施规程描述了用于评估乘用车和轻型卡车轮胎的一些特征激励的设备的设计要求，这些特征激励可能会对车辆造成干扰。所处理的激励类型是由轮胎结构中的不均匀性引起的，并且在装有轮胎的车辆在平坦道路上行驶时会产生影响。本文件还描述了设备使用的一些广泛方面，并列出了根据当前经验采取的预防措施。 这些建议的目的是建立一个标准化的测量方法，供工程界使用。多年经验的证据支持使用所述设备类型和程序获得的数据的统计相关性。然而，由于温度、储存条件、表面污染以及之前的使用历史等原因，材料的机械不稳定性会导致振动激励发生变化。因此，单个轮胎的测量总是有一定程度的不确定性。然而，通常可以很好地确定较大的振动激励值，并且数据的统计评估通常有助于正确指示本文件中考虑的这些项目的轮胎生产批次的振动激励质量。 质量标准可能基于根据本文件进行的测量，遵循个别工程应用的需要，因此不足以在此规定。

The comfort and fatigue of vehicle passengers is a major engineering consideration. Among the many factors involved are vibratory and auditory disturbances. Tires participate, among other elements of the vehicle, in exciting vibrations and noises. Furthermore, tires also may generate forces leading to lateral drift of the vehicle.This SAE Recommended Practice describes the design requirements for equipment to evaluate some of the characteristic excitations of passenger car and light truck tires which may cause disturbance in vehicles. The kinds of excitations treated result from nonuniformities in the structure of the tire and have their effect when a vehicle bearing the tire travels on a smooth road.This document also describes some broad aspects of the use of the equipment and lists precautionary measures that have arisen out of current experience.The intention underlying these recommendations is to establish a standardized measurement for use by the engineering community.The evidence from years of experience supports the statistical relevance of data obtained using the type of equipment and procedures described. However, mechanical instability of materials in response to temperature, storage conditions, and surface contamination, as well as the previous history of usage, etc., produces variation in vibratory excitations. Thus, the measurements of individual tires are always to a degree of uncertain. Nevertheless, larger values of vibratory excitations are usually well identified, and statistical evaluations of the data usually serve to indicate properly the vibration excitation quality of production lots of tires for those items considered in this document.Criteria of quality which might be based on measurements made under this document follow from the needs of individual engineering applications and are consequently not sufficiently general to be specified here.
