Nonlinear Model for Landing Gear Shimmy

, 1991
In the landing gear of a taxiing aircraft, shimmy is a condition of self-excited oscillation driven by the interaction between the tire and the ground. In extreme cases shimmy can cause severe damage to the landing gear hardware or even the loss of the ...

A new approximate model of tyre accounting for both deformed state and dry friction forces in the contact spot on the background of the coupled model

MATEC Web of Conferences, 2018
A new approximate model of the tire rolling accounting for coupled longitudinal and lateral sliding as well as the spinning and the deformed state resulting in elastic forces is proposed.

Active Control of Shimmy in Articulated Single-Axle Straddle-Type Monorail Train

Machines
The articulated single-axle straddle-type monorail train has many unique advantages, making it the preferred choice for medium-capacity urban rail transit. However, the issue of vehicle shimmy greatly restricts its promotion and application.

On the Shimmy Motion of Tire Wheel

Transactions of the Japan Society of Mechanical Engineers, 1951
In this paper the theoretical equation of motion of tire wheel is obtained, by the consideration of tire deformation and the slip against road, as a method to connect the Kantrowitz's shimmy equation and the usual theory which neglects the tire deformation. This equation leads to the steering characteristics of pneumatic tire.

Shimmy model for electric vehicle with independent suspensions

, 2017
A 5-degrees-of-freedom shimmy model is established to analyse the dynamic responses of an electric vehicle with independent suspensions. Tyre elasticity is considered by means of Pacejka's magic formula.
