Aerodynamic analysis of an isolated vehicle wheel
Increasing fuel prices force the manufacturers to look into all aspects of car aerodynamics including wheels, tyres and rims in order to minimize their drag. By diminishing the aerodynamic drag of vehicle the fuel consumption will decrease, while driving safety and comfort will improve. In order to properly illustrate the impact of a rotating wheel aerodynamics on the car body, precise analysis...
متن کاملLateral Stability Analysis of High-Speed Railway Vehicle on Curve
A vehicle body, two bogie frames and two wheelsets for each bogie frame are used to describe the railway vehicle model. The system dynamic is modeled using a 38-DOF system including the longitudinal, lateral, vertical, roll, pitch and yaw displacements. A heuristic nonlinear creep model and the elastic rail are used to simulate the wheel-rail contact. Stable movement and the corresponding limit...
متن کاملRobust Stability Analysis for Connected Vehicle Systems
For implementation in real traffic, connected vehicle systems should be designed to be robust against uncertainties arising from human-driven vehicles. Assuming that the bounds of uncertainties are known, we propose a frequency domain approach to guarantee robust string stability and to select optimal control parameters. The method is demonstrated by two case studies.
متن کاملStability Analysis of Nonlinear Connected Vehicle Systems
In this paper, we investigate the nonlinear dynamics of connected vehicle systems. Vehicle-to-vehicle (V2V) communication is exploited when controlling the longitudinal motion of a few vehicles in the traffic flow. In order to achieve the desired systemlevel behavior, the plant stability and the head-to-tail string stability are characterized at the nonlinear level using Lyapunov functions. A m...
متن کاملOn the dynamic stability of a flying vehicle under the follower and transversal forces
This paper deals with the problem of the instability regions of a free-free uniform Bernoulli beam consisting of two concentrated masses at the two free ends under the follower and transversal forces as a model for a space structure. The follower force is the model for the propulsion force and the transversal force is the controller force. The main aim of this study is to analyze the effects of...
