摘要
提出了一种包括任意垂直载荷分布的轮胎在纵滑与侧偏联合工况下的力与力矩的统一模型。该模型可归结为无量纲合力与无量纲综合滑移率的关系,因此简化了试验结果的归纳与整理,并可从较易行的单纯侧偏试验结果中推断出侧偏与纵滑联合工况下的无量纲力学特性,从而为汽车在转向、制动、驱动及其联合工况下动力学的模拟研究奠定基础。文中同时给出了一些轮胎台架试验结果和汽车转弯制动试验结果,并与按模型计算的结果作了比较。
This paper presents a unified tire moded for generating forces and moments under combined conditions of longitudinal and ldteral slip. A unified relationship between the nondimensional resultant force and moment, and the normalized resultant slip vector, with an arbitary vertical load distributton over the contact patch, is derived. Hence, the processings of test data are greatly simplifized, and parameters of the combined characteristics can be identified from the pure sideslip tests. It provides an import...
