Analysis of nose landing gear shimmy based on multi-body dynamics simulations

Key Points

The proposed simulation method identifies shimmy damping values critical for nose landing gear stability.
Results highlight how variations in tire force and structural stiffness affect the shimmy dynamics.
The study leverages multi-body dynamics simulations to evaluate the complex interaction of multiple variables.
Findings support the design of more stable nose landing gear systems for UAV applications.

Abstract

Abstract With the nose landing gear of a certain type of UAV being the research object, a multi-body dynamics simulation method for nose landing gear shimmy is proposed in this paper. Considering the influence of multiple variables such as air spring force, hydraulic damping force, tire force, and structural stiffness in nose landing gear, the shimmy damping value that can meet the requirements of shimmy stability of nose landing gear is output.
