Dynamic Analysis of a Partially Filled Tanker Train Travelling on a Curved Track

This article studies the dynamic analysis of a partially filled tanker train traveling on a curved track. The article describes how a partially filled tanker is dynamically modeled when it is traveling along a real curved track. For three classes of tracks, rail irregularities are randomly generated by using Monte Carlo simulation. An equivalent dynamic system is used to model the sloshing motion of the fluid. Two derailment indexes, derailment quotient and unloading ratio, are obtained numerically as safety indicators. A parametric study is carried out in order to investigate how different parameters such as the operational speed, fluid modeling, rail irregularities, and fluid density may affect the derailment potential. It is found that ignoring the sloshing may lead to 18% and 25% error in the calculation of derailment quotient and unloading ratio, respectively. The article found that lowering the center of gravity and consequently reduction of the moment arms is more dominant than the oscillating forces due to sloshing motion.
