Nonlinearities in landing gear model incorporating inerter

An inerter is a recently proposed two-node element in which the force across the two nodes is proportional to their relative acceleration. Studies based on linearization have previously been conducted on the application of inerters to landing gear for light civil aircraft to improve the resistance of such gear to shimmy vibration. Thus, the current research determines the effect of nonlinearities on the performance of the proposed model for aircraft landing gear in such vibration. This model is analyzed through a Simulink simulation, and conclusions are drawn on this effect and on the well-posedness of the linearized model.
