In this paper the formula of requisite linear damping for overcoming shimmy is derived according to the point contact theory of wheelshimmy.
本文根据机轮摆振的点接触理论，导出了为克服摆振所需线性阻尼的计算公式。

For the same automobile, the vibration degree or even the type of front wheelshimmy will change with the changing of the whole automobile constructs.
同一台车，整车结构发生变化时会改变前轮摆振的激烈程度以至振动的性质。
