本文按简化理论扼要地推导了为消除机轮摆振所需线性阻尼系数的计算公式。然而,实际使用的液压减摆器并不符合线性特性的假定,而是呈非线性特性的。对于这种实际情况,为了能将实际采用的非线性减摆器的阻尼系数和理论计算所需提供的线性阻尼系数加以比较,以评定能否克服摆振。本文提出了两种处理方法——切线法和最小当量线性阻尼法。实际应用表明,这两种方法简便、可靠,适于工程上使用。
Based on the simplified theory, this paper deduces the calculation formula of the linear damping coefficient needed to eliminate the wheel shimmy. However, the actually used hydraulic dampers do not conform to the assumption of linearity, but exhibit non-linearity. In this case, in order to be able to compare the damping coefficient of the actually adopted nonlinear dampener with the linear damping coefficient required for the theoretical calculation, it is possible to evaluate whether the oscillation can be overcome. In this paper, two methods are proposed - tangent method and minimum equivalent linear damping method. Practical application shows that these two methods are simple, reliable and suitable for engineering use.
