Local nonlinearities of airplane landing gears are considered. Analytical formulas and results of analysis of torsional stiffness and damping of a landing gear strut with local nonlinearities (free-plays, shimmy damper nonlinearities, seals friction) are presented. Shown also the results of analysis of shimmy stability boundary and limit cycles oscillations under dry and quadratic nonlinear friction by means of methods based on Routh-Hurwitz procedure, solution of full eigenvalue problem of shimmy linear equations matrix, as well as on D-partition of torsional dynamic stiffness plane for landing gear strut.
