摘 要:轮胎允许匹配安装多种型号车轮,装不同车轮所表现出来的性能会有所差异,本文对同一个轮胎装配不同宽度车轮方案进行参数测试,主要包含轮胎轮廓、轮胎接地印痕、车轮静态刚度、车轮力学性能;将测试结果用于整车动力学模型进行操控稳定性分析,同时将各方案装于整车上进行客观和主观测试。分析车轮参数、仿真分析结果、整车测试结果之间的关联。总结出轮胎装不同宽度车轮其在整车上的操纵性能变化规律,用于指导汽车设计过程中车轮型号的选择。

Abstract: The tires are allowed to be matched with multiple types of wheels, and the performance of different wheels will be different. This article including the test of parameters when the same tire is assembled with wheels of different width, parameters mainly including tire contour, tire grounding mark, and wheel static stiffness, wheel mechanical properties; the test results are used in the vehicle dynamics model for handling analysis, and at the same time, each assembly is installed on the vehicle for objective and subjective testing. Analyze the correlation between wheel parameters, simulation analysis results, and vehicle test results. Summarizes the law of how the vehicle handling performance changes when the tire matching with wheels of different width, which can be used to guide the selection of wheel models in the car design process.
Key Words: Tire; Wheel; Match Tire And Wheel; Handling Performance
引 言
轮胎与车轮安装匹配有规格型号的要求,首先要求两者的名义直径相同;对于车轮宽度的匹配,按国标GB/T2978规定,每个型号轮胎可以匹配三种宽度车轮,其中一个是测量推荐型号。
装配不同宽度车轮对轮胎的轮廓形状、接地印痕会产生怎样的影响?是否会影响轮胎的静态和动态刚度?对轮胎力学性能是否有影响?对轮胎的性能表现是怎样的影响等等?是否可以通过调整车轮的宽度来实现不同的性能诉求,目前行业内暂无相应的研究结论。
本文针对以上问题进行相关的研究,为后续轮胎与车轮型号的匹配提供设计指导。
1 研究思路
本研究主要以试验和分析为主。课题思路见图1,试验标的选取常用轮胎型号,搭配国标GB/T 2978规定的相对应的车轮,将这些搭配方案按同样条件进行台架和实车试验,对比分析试验结果,总结规律。……
