The Buffer System Dynamics Simulation Of Aircraft Landing Gear

We still adopt traditional method about the design and analysis of landing gear buffer system at present in China. We seldom use the software to analysis the dynamic behavior for airplane landing gear. The design platform of digital model of landing gear based on simulation software has a bright future.This paper begin with the concept system and system simulation, treat the landing gear as a system, use the concept of system simulation to establish the mathematical models of the landing gear, and to begin the simulation research. Also, compare many ways of simulation. In the course of establishing the mathematical models, the dynamics basic theory is applied. And three kinds of landing gear mathematical models are established. Many parameters' effects are considered, and many simulations are used to analyze and explore the results of the simulation model. At last, an available landing gear simulation software is developed, and different simulation results are made through modify the parameters.
