摘要
前轮定位参数对前轮摆振的影响是极其复杂的,它不仅影响了前轮的几何特性,并且对摆振系统的运动,约束与受力状况均产生重要影响。本文建立了包括全部前轮定位参数的前轮摆振数学模型;并在轮胎试验的基础上,比较系统、全面地研究了前轮定位参数对前轮摆振的影响规律。本文还研究了轮胎蛇形运动频率对汽车动力学摆振的影响。
The influence of alignment parameters of front wheel on shimmy isvery complicated. These parameters exert a great influence not only ongeometric and kinematic characteristics of the front wheels, but also onrestrained and dynamic characteristics of the shimmy system. The ma-thematical model of a whole shimmy system, consisting of all alignmentparameters, is established. On the basis of dynamic tire testing, thepattern of influence of alignment parameters on shimmy is studied sys-tematically and completely. The influence of the tire meandering fre-quency on vehicle dynamic shimmy is also studied.
