Abstract
This report presents a theoretical study of the behavior of the conventional type of oleo-pneumatic landing gear during the process of landing impact. The basic analysis is presented in a general form and treats the motions of the landing gear prior to and subsequent to the beginning of shock-strut deflection. The applicability of the analysis to actual landing gears has been investigated for the particular case of a vertical landing gear in the absence of drag loads by comparing calculated results with experimental drop-test data for impacts with and without tire bottoming. The calculated behavior of the landing gear was found to be in good agreement with the drop-test data.

Analysis of Taxiing Induced Vibrations in Aircraft by the Power Spectral Density Method

TL;DR: In this paper, the authors developed a method of analysing random vibrations of a flexible aircraft, taking account of nonlinearities in the oleo-pneumatic undercarriage in the form of orifice damping and Coulomb friction.

Oil compressibility and polytropic air compression analysis for oleopneumatic shock struts

TL;DR: In this article, a review of available literature shows that effects on shock absorption characteristics due to hydraulic fluid compressibility, gas solubility and its en trainmen t-in-oil, and the nature of polytropic exponent during the compression stroke are often neglected by the designer.

Analysis of Landing Gear Behaviour for Trainer Aircraft

TL;DR: In this paper, an approach to the application of ADAMS in the analysis of landing gear behavior and ground manoeuvring characteristics of a trainer aircraft is presented, with the first step taken towards the implementation of the aircraft model was that of separately recreating the behaviour of the auxiliary and main landing gear during drop-testing.

Including Inerters in Aircraft Landing Gear Shock Strut to Improve the Touch-down Performance

TL;DR: In this article, the authors presented the possibility of using inerter-based shock strut in a landing gear to improve aircraft touch-down performance, which is a mechanical element that the applied force is proportional to the relative acceleration between its terminals.
