| 摘 要： | 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。然而,液压减摆器的阻尼特性大都是非线性的。为此,本文提出了两种处理方法,即切线法和最小当量线性阻尼法,并找出了它们的关系。计算结果表明这些方法是有效而可靠的。

| Abstract: | In this paper the formula of requisite linear damping for overcoming shimmy is derived according to the point contact theory of wheel shimmy.However damp-ing property of the hydraulic shimmy damper is mostly non-linear. Two methods have been presented in this paper to treat this case. They are tangent method and minimum equivalent linear damping method.Their relation has been found, too. It has been demonstrated by computation that the methods are both effective and reliable. |
