Abstract

This paper proposes a method of optimizing the cushion properties for a certain amphibious aircraft landing gear, which is establishing an accurate simulation model in least mean square by adjusting parameters. First, carry out a drop test under initial parameters to get the friction between the tire and platform, and the elastic parameters of the wheel to simulate the interactions of components. Second, repeatedly modify the model by analyzing the results of comparisons between the drop test and simulation until an accurate model with optimal parameters is established. Finally, verify that the cushion properties of the landing gear with the optimal parameters meet the requirements of airworthiness rules and the properties are greatly improved. The study shows that an adjusting-parameter drop test for establishing a simulation model is an available and reliable way to optimize the cushion properties of an amphibious aircraft landing gear.
