标准摘要
[中文适用范围]: 本 SAE 推荐实践描述了三种测试方法,用于确定基本轮胎尺寸(几何形状)@质量@和惯性矩。这些方法适用于任何轮胎,只要设备经过适当缩放以对预期的测试轮胎进行测量即可。这些数据适用于确定道路荷载模型的参数以及对研发中测量的特性进行比较评估。注:这里的道路负载模型是用于预测在铺砌或未铺砌的不规则表面上运行期间施加到车辆主轴上的力的模型。在本推荐实践的背景下,不考虑施加到轮胎运行表面上的力。程序 指定了三个程序。第一个程序确定轮胎的未偏转半径@截面宽度@和截面高度。第二个参数确定轮胎和安装轮胎的车轮的质量。第三个过程确定推荐实践 SAE J2710 中定义的三个笛卡尔轴的转动惯量。测试机器 尽管个别测试实验室可能拥有特定用途的测试机器来进行某些测量@例如@惯性,但使用本推荐实践中的程序不需要特定用途的测试机器。每个程序都可以使用特定的夹具和工具组合来应用。每个特定程序的描述的“所需测量工具”部分中指定了适合每个程序的示例工具和夹具。 [外文原描述]: This SAE Recommended Practice describes a trio of test methods which determine basic tire size (geometry), mass, and moments of inertia. The methods apply to any tire so long as the equipment is properly scaled to conduct the measurements for the intended test tire. The data are suitable for determining parameters for road load models and for comparative evaluations of the measured properties in research and development.NOTE: Herein, road load models are models for predicting forces applied to the vehicle spindles during operation over irregular surfaces paved or unpaved. Within the context of this Recommended Practice, forces applied to the surface on which the tire is operating are not considered.Cross Reference: 770870,810066,ASTMF1502,FMVSS139,ISO/IEC17025,J2047_201303,J2047_201911,J2429_201509,J2710_201204,J2710_201709,OSHA1910.177
