THE YAW STABILITY OF LOG HAULING COMBINATION TRUCKS

Transactions of the Canadian Society for Mechanical Engineering, 1993
A planar mathematical model for various design configurations of tractor-jeep-pole trailer combinations, incorporating a sliding drawbar, is developed. A kinematic and dynamic analysis for this vehicle combination is then carried out and a computer simulation model is developed.

Influence of Yaw Cards on the Yaw Growth of Spin-Stabilized Projectiles

Journal of Aircraft, 2001
A simple extension of the standard linear theory, describing the free-flight motion of a projectile, now includes the influences due to the projectile impacting yaw cards. The card impacts are modeled as ideal delta function impulses that are shown to alter the usual yawing motion of a spin-stabilized projectile passing through a yaw card range.

Yaw Axis Stability Augmentation System Flight Test Report

1974
Abstract : The report describes the design and flight tests of a hydrofluidic yaw stability augmentation system (SAS) for an OH-58A helicopter. The design objective was to improve stability characteristics in yaw for all flight conditions from hover to 120 kn. The yaw SAS, which initially featured only high-passed yaw rate feedback, was installed in an

Yaw/Roll Stability Modeling and Control of HeavyTractor-SemiTrailer

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">This paper sets up a simplified dynamic model for simulating the yaw/roll stability of heavy tractor-semitrailer using Matlab/Simulink. A linear quadratic regulator (LQR) based on partial-state feedback controller is used to optimize the roll stability of the vehicle.

Vehicle yaw stability control using the fuzzy-logic controller

2007 IEEE International Conference on Vehicular Electronics and Safety, 2007
The yaw stability of a vehicle is crucial to vehicle safety in steering manoeuvres. In this paper, a fuzzy-logic controller is designed for improving vehicle yaw stability by corrective yaw moment generated from differential braking so that the yaw rate and body sideslip angle can trace their desired values.

A new pitch/yaw stabilized bathymetric survey system

OCEANS 2000 MTS/IEEE Conference and Exhibition. Conference Proceedings (Cat. No.00CH37158), 2002
There is an increasing need in the oil and gas industry, as well as the ocean research community, for mid to deep ocean survey systems that compensate fully for vessel pitch, roll and yaw motion. To respond to this requirement, L-3 Communications SeaBeam Instruments/ELAC Nautik are developing a new wide swath bathymetric sonar system.

Limit cycle stability of aerodynamically induced yaw oscillations

International Journal of Mechanical Sciences, 1979
Abstract The aerodynamic yaw moment is written generally as a Taylors-Fourier series. Truncation of the series and assembly of the model leads to a second order non-linear differential equation which bears some similarity to the Van der Pol equation. The system is then examined both on the phase plane and by an approximate stability analysis.

Yaw stability control of commercial vehicle based on variable stability region

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science
Yaw stability is a core issue in commercial vehicle(CV) driving safety, especially in the emergencies and extreme conditions. This study aims to address it with the concept of variable stability region (VSR) in dynamic and unpredictable conditions. The critical boundary of yaw stability is analyzed through the Routh-Hurwitz criterion with the impact of
