Abstract
A comparison between tank- truck and heavy- freight vehicle accidents shows a 50% higher participation of tank- trucks in front /rear collisions on motorways as well as in single- vehicle accidents and in frontal collisions on the highways. It is assumed that shifting cargo, particularly liquid loads, liquid sloshing'could be one of the causal factors of such tank- truck accidents. The interaction between liquid sloshing and the accident characteristics of tank- trucks shall be investigated with the help of the driving simulator. A real- time analysis of liquid sloshing demands a simple, yet precise mathematical description.
