Abstract
The study of dynamics of tank vehicles carrying liquid fuel cargo is complex. The forces and moments due to liquid sloshing create serious problems related to the instability of tank vehicles. In this paper, a complete analytical model of a modular tank vehicle has been developed. The model included all the vehicle systems and subsystems. Simulation results obtained using this model was compared with those obtained using the popular TruckSim software. The comparison proved the validity of the assumptions used in the analytical model and showed a good correlation under single or double lane change and turning manoeuvers.

The forces and moments due to liquid sloshing create serious problems related to the instability of tank vehicles
Different simple models for tractors and trailers have been described in literatures to study the dynamic behavior of heavy vehicles during various maneuvers
Summary
Numerical models are developed to understand the liquid sloshing phenomenon coupled with tank structure They are able to determine the coupling behavior, only under specific conditions, such as periodic accelerations. While various solid-liquid models have been developed to determine the dynamic behavior of vehicles carrying liquids, few models have been developed to reflect the effects of vehicle systems and subsystems, such as suspension and tire components. The TruckSim software does not include the effects of motion of a moving load [6,7,8] They are easy to use for conventional vehicles only. They offer some models for unconventional designs and the models find applications in some specific research projects. The present work focussed on development of custom made models
