轮胎动态侧偏特性对汽车摆振的影响

The Influence of Dynamic Characteristics of Tire Lateral Distortion on Shimmy of Motor Vehicle

轮胎的动态侧偏力学特性是影响汽车前轮摆振的最关键因素之一。文中在长春汽车研究所提出的轮胎动态侧偏特性试验方法的基础上，建立了测向力与回正力矩的精确表达式，并从能量反馈和负阻尼效应观点研究了轮胎动态侧偏特性参数对汽车摆振的影响。

Dynamic characteristics of wheel tire lateral distortion mechanics of motor vehicle is one of the most important key factors influencing the front wheel shimmy of the motor vehicle.Accurate expression for the relationship of tire cornering force and self aligning moment has been established on the basis of the testing method of tire dynamic lateral distortion characteristics which the author brought forward in the Changchun Automotive Research Institute- Also the in-fluence of the parameters of tire dynamic characteristics of lateral distortion on shimmy of motor vehicle has been studied from the view of energy feedback and negative damping effect.
