Shimmy Analysis of Differential Steering-by-Wire System for Electric Vehicles with In-Wheel Motors and Steering Trapezoidal Mechanism

SAE technical paper series
The differential steering-by-wire (DSBW) system eliminates the need for steering gear, i.e., rack and pinion, while preserving a trapezoidal steering structure with knuckles.

Dynamic modeling and behavior analysis of vehicle shimmy system considering the rubber bushing

Proceedings of the Institution of mechanical engineers. Part D, journal of automobile engineering
Vehicle shimmy is a harmful vibration phenomenon that significantly affects vehicle stability and safety. Unlike previous studies that typically neglected the influence of suspension rubber bushings, this paper focuses on the rubber bushing at the ...

Influence of clearance and structural coupling parameters on shimmy stability of landing gear

Aeronautical Journal, 2023
There are many factors causing the shimmy of the aircraft landing gear and structural clearance of landing gear is a typical factor. Some aircraft in service or operation did not shimmy before, but suddenly appeared after a period of use.

Subcritical Bifurcations in Shimmy Dynamics

AIAA Atmospheric Flight Mechanics Conference, 2012
When wheels are rigid relative to other parts of the supporting structure, complex shimmy phenomena can be described by single-contact-point models and the equations of motion of the corresponding nonholomic systems can be derived by means of Appell-Gibbs equations.

Aircraft Nose Landing Gear Shimmy with Nonlinear Tire Models

International Journal of Bifurcation and Chaos in Applied Sciences and Engineering
In this study, an application of a nonlinear tire model is considered in the analysis of aircraft nose landing gear shimmy. An aircraft single-wheel nose landing gear system is used to analyze the shimmy stability, where the tire model is designed to ...

Parametric shimmy of a nosegear

Journal of Aircraft, 1970
Thus, the theoretical two-dimensional time-dependent solution, Eq. (9), has been tested as a description of the viscous cross flow for large fineness ratio bodies approximating circular cylinders at moderate angles of attack. Some agreement has been obtained, although empirical procedures are still required and the region of applicability is narrow ...
