Roll Dynamic Response of an Articulated Vehicle carrying liquids
The directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. The dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank mode...
متن کاملA Simple Model for the Determination of Jackknifing
Jackknifing is uncontrolled braking of a truck-trailer combination which causes the trailer rotates relative to tractor and as a result extends to adjacent lanes, causing in many cases sever accidents. In this paper a simple two dimensional model is presented. The model includes parameters such as truck’s and trailer’s dimensions, coefficients of friction, masses, location of the load on the tr...
متن کاملStudy on Tractor Semi-Trailer Roll Stability Control
The rollover accidents in the tractor semi-trailer are often fatal and many factors could cause the tractor semitrailer rollover. In this paper, a rollover prevention control method was proposed based on real-time calculation of rollover index. The vehicle Center of Gravity CG height from the ground is an important parameter in the rollover index and it is estimated through lateral acceleration...
متن کاملComparative Computational Analysis of Drag-reducing Devices for Tractor-trailers
Constant rise in fuel price in recent times has caused manufacturers of heavy commercial vehicles (HCV) to turn to efficient aerodynamic design of trucks, wagons, tractors as well as trailers. The comparative analysis in this study compares the coefficient of drag of the following four aerodynamic configurations of a tractor-trailer combination: 1. Semi-trailer with no devices. 2. Semi-trailer ...
متن کاملOptimal Reconfiguration Control of the Yaw Stability of the Tractor-Semitrailer Vehicle
An optimal reconfiguration control scheme based on control allocation CA is proposed to stabilize the yaw dynamics of the tractor-semitrailer vehicle. The proposed control scheme is a twolevel structure consisting of an upper level of sliding mode yaw moment controller SMYC and a lower optimal brake force distributor BFD . The upper SMYC is designed to follow the tractor yaw rate and the combin...
