Design and Verification of an Aircraft Landing Gear Taxiing Test System

In order to study the dynamic characteristics of aircraft landing gear, a semi-physical simulation taxiing test system for aircraft landing gear is proposed, to simulate aircraft taxiing on different runway in the laboratory. The dynamic performance of aircraft landing gear test bench is analyzed by using finite element method and MSC.Patran/Nastran software. In order to avoid the coupling between the excitation frequency of the test loading equipment and the first natural frequency of the bench, Method of optimizing parameters is used to improve natural frequency of the bench, and EASY5 is used to model and simulate the hydraulic system of the aircraft landing gear taxiing test system. The results show that the dynamic performance and strength of the optimized bench meet the design requirements, and the hydraulic system simulation results are basically consistent with the actual operation.
