卡客车轮胎自由滚动转弯试验

[中文适用范围]： 本 SAE 推荐实践描述了测定重型卡车（VI、VII 和 VIII 级）轮胎在转弯条件下的力和力矩特性的测试方法。使用本实践中指定的序列来获取作为法向力和滑移角的函数的属性。在每个法向力增量处，滑移角连续地倾斜或阶跃。这些数据适用于车辆动力学建模、研发比较评估以及制造质量控制。本文档旨在成为在理想机器上进行测试的一般指南。本 SAE 推荐实践的用户可以修改推荐协议以满足特定用例的需求，例如，减少用于基准测试目的的推荐测试负载和/或压力数量。然而，在修改协议以维护数据完整性时，必须小心谨慎。 [外文原描述]： This SAE Recommended Practice describes a test method for determination of heavy truck (Class VI, VII, and VIII) tire force and moment properties under cornering conditions. The properties are acquired as functions of normal force and slip angle using a sequence specified in this practice. At each normal force increment, the slip angle is continually ramped or stepped. The data are suitable for use in vehicle dynamics modeling, comparative evaluations for research and development purposes, and manufacturing quality control.This document is intended to be a general guideline for testing on an ideal machine. Users of this SAE Recommended Practice may modify the recommended protocols to satify the needs of specific use-cases, e.g., reducing the recommended number of test loads and/or pressures for benchmarking purposes. However, due care is necessary when modifying the protocols to maintain data integrity.Cross Reference: 760029,770870,810066,960180,962153,CRP-11,J2047_201911,J2673_202103,J2675_201711,J670_202206
