Abstract

Abstract:

For the elastic structure characteristics of aircraft landing gear, a dynamic model is established. Meanwhile, the problem is analyzed with the discrete structure simplified response. The Hamilton's variation principle is used for putting forward the landing dynamic model containing the elastic structure. According to the dynamic model, the number of discrete structures of landing gear can be free to choose for solving the dynamics equation and analyzing the response. Taking the analysis of aircraft landing process as an example, with the use of random simulation, through the simulation of the aircraft landing sinking speed, initial displacement and runway unevenness, the random response characteristics of the aircraft are analyzed on the landing. The actual dynamic performance and the stress-strain characteristics of landing gear are determined, providing a basic reference for the optimization of structure parameters and fatigue analysis of landing gear.
