| 摘 要： | 轮胎的侧偏力学特性是前轮摆振发生的主要原因。通过比较两种都带轮胎侧偏特性的不同轮胎运动方式,对比分析两种运动的轮胎力做功,解释为什么轮胎力做功不同;从而说明轮胎在摆振运动中做正功,不断吸收能量体现轮胎负阻尼特性,所以发生轮胎自激型摆振。

| Abstract: | mechanical characteristics of the tire lateral distortion is one of the most important key factors influencing the front wheel shimmy. In this paper, two different tire movement were compared all with the tire lateral distortion. The work of the tire force were analyzed in the both movements.And explain why the work of the tire force were different. Thus illustrate the tire force do positive work in shimmy motion,can absorb energy continuously,and reflect the tire negative damping characteristics. So self-excited tires shimmy occurred. |

| Keywords: | front wheel shimmy tire lateral distortion tire force negative damping characteristics |
