Development of a new algorithm for fluid sloshing-vehicle dynamic coupled simulation and its experimental validation

Abstract

Traditional methods for analyzing the dynamics of fluid-carrying vehicles such as pendulum or mass–spring models do not yield accurate results, thus seeking new methods for investigating the dynamics of these vehicles is desirable. The objective of this study is to find a new methodology for handling the dynamics of such systems. In this paper, an algorithm is proposed by which a data bridge is implemented between two commercial software programs such that a coupled simulation of the carrier and fluid dynamics is achieved. Unlike alternative mechanical models, the most important feature of this method is its validity during all events regardless of carrier position and orientation. Finally, this approach is validated by experiments. Experimental results are in excellent agreement with simulations. In addition, unlike existing algorithms, the proposed algorithm is numerically stable.
