１前言汽车转向轮摆振问题是汽车在设计开发过程中最易出现的问题之一。所谓转向轮摆振是指汽车在平坦的路面上行驶时所产生的转向轮绕主销持续的振动现象。摆振问题的存在 ,不仅使汽车操纵性、平顺性变坏 ,而且也会使轮胎及转向系统的构件出现早期磨损 ,还额外增加了滚动阻力
1 Preface The car steering wheel shimmy problem is one of the most prone to the car during the design and development process. The so-called steering wheel shimmy refers to the continuous vibration of the steering wheel around the kingpin when the car is driving on a flat road surface. The existence of the shimmy problem not only deteriorates the maneuverability and ride comfort of the vehicle, but also causes early wear of the components of the tire and the steering system and additionally increases the rolling resistance
