Abstract
1. An Evaluation on Damping Property of Non-linear Shimmy Damper and Equivalent Linearization Methods: This paper derives the formula of requisite linear damping for overcoming landing-gear shimmy according to the point-contact theory. However, the damping property of the hydraulic shimmy damper is mostly non-linear. Two methods are presented to treat this case: The tangent method and the minimum equivalent linear damping method. Their correlation is also found. It is demonstrated by computation that both methods are effective and reliable. 2. A Study on Approaches for Data Treatment of Measured Ground Loads on Airplanes: This paper discusses the requirements for measuring ground load on an aircraft. A practical data treatment method has been developed for the case that the measurement satisfy the minimum requirement. Although the method is illustrated with taxiing data in this paper, however, it is also applicable to the treatment of turning and braking load data. Chinese translations.
