TLDR
In this paper, a nonlinear model of the mechanics of the landing gear and tire elasticity according to elastic string theory is applied to the shimmy analysis of a simple model of a nose gear: computing eigenvalues, solving analytically the stability boundaries with a parameter space method, and last but not least numerical simulation of time histories.About:

Multiple-Input Describing Functions and Nonlinear System Design
TL;DR: The theory of automatic control has been advanced in important ways during recent years, particularly with respect to stability and optimal control, but these theories do not, however, lay to rest all questions of importance to the control engineer.

Tyre Modelling for Use in Vehicle Dynamics Studies
TL;DR: In this paper, a new way of representing tyre data obtained from measurements in pure cornering and pure braking conditions has been developed in order to further improve the Dynamic Safety of vehicles, making use of a formula with coefficients which describe some of the typifying quantities of a tyre, such as slip stiffnesses at zero slip and force and torque peak values.
