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 model. ...

This paper addresses the problem of path plannrng using a dynamic vehicle model. Previous works which include a basic kinematic model generate paths that are only realistic at very low speed. By considering higher vehicle speed during navigation, the vehicle can significantly deviate from the planned trajectory. Consequently, the planned path becomes unusable for the mission achievement. So, to...

Recently, a number of authors have been focusing on drive-by monitoring methods, exploiting sensors mounted the vehicle rather than bridge to be monitored, with clear advantages in terms cost and flexibility. This work aims at further exploring feasibility effectiveness novel tools for indirect health railway structures, by introducing higher level accuracy damage modelling, achieve more close-...

High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

A configuration of a single-phase full-bridge AC-DC converter and dual active bridge (DAB) converter used in V2G (vehicle to grid) and G2V (grid to vehicle) technology is proposed in this paper. It can well realize the bi-directional energy fluidity. The numerous controllers can be designed by MATLAB SISOTOOL easily and quickly. And PLECS software is used to validate the function of the propose...

SYNOPSIS Advanced bridge analysis and design methods have been simplified with the aid of modern bridge software. This paper provides a summary of these new analysis and design methods and the advantages that can be achieved. Topics covered include automated vehicle load pattern generation methods to the new Australian Bridge Code (AS5100) and the New Zealand Transit Manual, recent developments...

System identification technique is used widely in the damage assessment of engineering structures. It is regarded as the key part of a structural health monitoring system, which identifies the physical parameters from the raw measurement data. The changes in the identified parameters will be used to assess the damage of the structure. Most system identification methods need the input loading an...

Bridge rails are a type of longitudinal barrier that serves the important purpose of keeping vehicles on the bridge structure. Many different designs have evolved for bridge rails, including some based upon the cross sections used for rigid concrete safety shapes. These designs need to conform to the crashworthiness requirements of NCHRP Report 350 or MASH to be acceptable for use on U.S. highw...
