In this paper the formula of requisite linear damping for overcoming shimmy is derived according to the point contact theory of wheel shimmy.
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。

However damping property of the hydraulic shimmy damper is mostly non-linear.
然而，液压减摆器的阻尼特性大都是非线性的。

Moreover, increasing the stiffness and damping of lower control arm rear bushing and the steering column inertia can effectively reduce the shimmy caused by brake judder.
