用于方向控制研究的车辆和悬架参数测量

[中文适用范围]： 根据本 SAE 推荐实践测量的参数通常用于模拟线性范围内的方向控制性能。 （“线性范围”是稳态横向加速度，低于该加速度通常可以认为方向盘角度与横向加速度线性相关。）但它们可用于某些其他模拟（例如主要行驶运动）、车辆和悬架特性和比较、悬架开发和优化以及道路测试数据的处理。本文件适用于乘用车、轻型卡车以及公路休闲车和商用车，包括非铰接式和铰接式车辆。测量技术旨在应用于这些车辆，主要改变所需设施的规模。 [外文原描述]： The parameters measured according to this SAE Recommended Practice will generally be used in simulating directional control performance in the linear range. (The “linear range” is the steady-state lateral acceleration below which steering wheel angle can generally be considered to be linearly related to lateral acceleration.) But they may be used for certain other simulations (such as primary ride motions), vehicle and suspension characterization and comparison, suspension development and optimization, and processing of road test data.This document is intended to apply to passenger cars, light trucks, and on-highway recreational and commercial vehicles, both non-articulated and articulated. Measurement techniques are intended to apply to these vehicles, with alterations primarily in the scale of facilities required. But some differences do exist between passenger cars and trucks, especially heavy trucks, such as differences in body/frame flexibility, suspension stiffness, and suspension friction. These will be addressed in this document or SAE J1574-2, where appropriate.Cross Reference: J1106,J1107,J1574-2,J1574/2_201801,J670_202206,J874
