This paper presents kinematic and dynamic analysis of a holonomic vehicle with continuously-variable transmission. Four ball wheels, independently actuated by DC motors, enable for moving the vehicle in any direction within the plane and rotating it around its center. The angle between the two beams holding the balls can be changed to alter the gear ratio and other dynamic characteristics of th...

This paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. Since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

Pneumatic‐hydraulic transmission has been developed for years. However, its dynamic properties are not good enough for application. In this paper, in order to increase the output characteristics, a late‐model air‐powered vehicle using expansion energy is proposed which can boost energy through a pneumatic‐hydraulic transmission. The dynamic characteristics of the air‐powered vehicle is modeled ...

Dynamic and stochastic vehicle routing problems are receiving more attention as both algorithms and computing technology advances. The dynamic aspects are important in many applications and research on practical algorithms is an area with increasing activity. We present a framework for representing dynamic and stochastic vehicle routing problems. The framework is intended for use in creating an...

ABSTRACT Two recently developed motion control algorithms for mobile manipulators are applied to an experimental system. The manipulator motions induce significant dynamic interactions with its vehicle and suspension. A conventional fixed-base controller, which typically neglects these dynamic interactions, is shown to lead to poor performance. Both mobile manipulator control algorithms, howeve...

NONLINEAR DYNAMICS OF LONGITUDINAL GROUND VEHICLE TRACTION By Brian John Olson The purpose of this study is to investigate and understand the nonlinear dynamics of longitudinal ground vehicle traction. Specifically, the performance of rubber-tired automobiles under straight-ahead braking and acceleration conditions is discussed in detail. Two vehicle-traction models are considered—a quarter-car...

Journal : European Journal of Operational Research State : Accepted manuscript doi:10.1016/j.ejor.2012.08.015 Abstract : A number of technological advances have led to a renewed interest on dynamic vehicle routing problems. This survey classiVes routing problems from the perspective of information quality and evolution. After presenting a general description of dynamic routing, we introduce the...

This paper studies the impact of fuel-cell (FC) performance and control strategies on the benefits of hybridization. One of the main weak points of the FC is slow dynamics dominated by a temperature and fuel-delivery system. Although many researchers have investigated the use of different powertrain topologies, component sizes, and control strategies in fuel cell vehicles, a detailed parametric...
