Abstract:
Regarding increasing importance of tank wagons and efficiency in fluids transportation, their usage is increasing everyday. Thus paying attention to their designs just as dynamic analysis of wagons during travelling time is vitally important.In this task, sloshing coefficient as prominent parameter in tank wagons designing has been investigated. To easeof efficient design, theses parameters can cause accurate and economic design. For purpose of derivation of this coefficient,Arbitrary Lagrange-Euler (ALE) method was applied and results were compared with equivalent mechanicalmethod (EM). So, to simulate fluid sloshing inside the tank two different approaches, Finite element method and multibody dynamics were exploited. In lateral and longitudinal simulations, tanker is analyzed in traveling curved trackand accelerating respectively. Also, the effects of velocity, irregularities of track and fill ratio on sloshing coefficientwere studied. These results are proposed to be used in tank design and related manuals.
