A Mono-axial Wheel Force Transducer for the Study of the Shimmy Phenomenon
نویسندگان
چکیده
The shimmy is an unstable oscillation of the whole castor wheel assembly about its king pin. The phenomenon originates from the castor motion and is mainly depending on the castor lateral flexibility and on the tire-road interaction. The paper analyzes the possibility to measure the tire lateral force by means of sensors that do not substantially change the inertial properties of the castor. A measuring system is proposed and discussed to highlight the operating conditions for which the measurements can be considered reliable and functional to investigate the dynamic behaviour. Finally some experimental results are presented and discussed.

Interaction of torsion and lateral bending in aircraft nose landing gear shimmy
In this paper we consider the onset of shimmy oscillations of an aircraft nose landing gear. To this end we develop and study a mathematical model with torsional and lateral bending modes that are coupled through a wheel-mounted elastic tyre. The geometric effects of a positive rake angle are fully incorporated into the resulting five-dimensional ordinary differential equation model. A bifurcat...
متن کاملA Study for Shimmy Reduction using Theoretical Multi-body Model and Experimental Techniques
In this study, both theoretical linear model and numerical model are used to predict and optimize the frequencies of shimmy related modes and the level of the vibration for a vehicle. A theoretical multi-body linear model of 32-DOF were used for quasi-static analysis and modal analysis. The theoretical model was verified by comparing the results of modal analysis with those of modal test for fr...
متن کاملWheelchair caster shimmy and turning resistance.
The equations for wheelchair caster wheel shimmy are presented along with experimental data. The report includes the theory and performance of single wheel casters for a variety of tires, and a new design for wheelchair casters using a grooved dual-tread tire or co-rotating caster wheels. The dual-tread tire was found to significantly inhibit caster shimmy. The turning resistance due to a groov...
متن کاملStability of Towed Wheels with Elastic Steering Mechanism and Shimmy Damper
This paper investigates a low degree-of-freedom wheel model, which describes the lateral vibration of towed wheels, called the shimmy. The model takes into account the lateral deformation of the tyre and also the torsional elasticity and the damping of the steering mechanism. The lateral deformation of the wheel is modeled by the stretched-string like tyre model, which considers the relaxation ...
متن کاملDelay effects in shimmy dynamics of wheels with stretched string-like tyres
a r t i c l e i n f o a b s t r a c t The dynamics of wheel shimmy is studied when the self-excited vibrations are related to the elasticity of the tyre. The tyre is described by a classical stretched string model, so the tyre-ground contact patch is approximated by a contact line. The lateral deformation of this line is given via a nonholonomic constraint, namely, the contact points stick to t...
