轮胎法向力/偏向力和总压痕尺寸试验

[中文适用范围]： 本 SAE 推荐实践描述了一种用于确定非滚动轮胎的垂直力和偏转特性以及相关接地面积长度和宽度的测试方法。该方法适用于任何轮胎，只要设备经过适当缩放以对预期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在研究和开发中对测量特性进行比较评估。注：这里的道路载荷模型是用于预测在不规则路面上运行期间施加到车辆主轴上的力的模型。在本建议实践的背景下@不考虑施加到人行道上的力。程序 指定了两个程序。第一个过程产生轮胎法向力/偏转数据。第二个程序产生总足迹@轮胎接触面积@尺寸。正确应用第二个程序可以同时生成法向力/偏转数据和总足迹尺寸。测试机器 本文档与测试机器无关。可以使用能够满足本文件中所述要求的任何类型的测试机器来应用它。测试机必须能够适应要测试的轮胎尺寸。 [外文原描述]： This SAE Recommended Practice describes a test method for determining the vertical force and deflection properties of a non-rolling tire and the associated contact patch length and width. The method applies 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 use in 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 pavements. Within the context of this Recommended Practice, forces applied to the pavement are not considered.Cross Reference: 770870,ISO17025,J2047_201911,J2429_201509,OSHAStandard191
