“…The equivalent mechanical models have been shown to be effective and simple to describe liquid sloshing. 16 In this section, the numerical solution of the liquid sloshing in lateral and longitudinal directions is solved based on approximate algorithms for the horizontal cylinder tank. It is assumed that baffles are not considered in the tank.…”

Additional slosh forces and moments are generated owing to the movement of the liquid inside a partly filled tank car. The loads may have a great influence on the structure reliability and dynamic performance of the vehicle. An improved equivalent model of liquid sloshing is put forward to obtain the forces and moments of sloshing liquid acting on the tank during the lateral and longitudinal sloshing processes. An improved method is proposed to obtain the equivalent masses and stiffness for the improved equivalent model. The equivalent model is integrated into the multi-body dynamic model of a railway tank car with 68 degrees of freedom. Furthermore, the equivalent liquid-vehicle model is used to investigate the effects of fluid sloshing on dynamic characteristics. The influence of the filling ratio on the dynamic response of the tank car is discussed based on the forces and the corresponding moments between the tank car body and the liquid in different layers. The railway tank car is obviously influenced by the liquid sloshing during passing the curved and sloped tracks. The influence of liquid sloshing on the pitching motion of the tank is heavy if the tank is about half filled. The derailment coefficient and the wheel unloading rate are slightly influenced by the filling ratio of tank cars on curved tracks while the indices of the tank cars on sloped tracks are the greatest if the filling ratio is 40%.

“…Therefore, the first sloshing modal is the most important one. More details about the dynamics of liquid sloshing in partially filled tanks without or with baffles can be found in Zheng et al [37][38][39] Equivalent mechanical model for liquid sloshing Dynamic analysis of liquid sloshing in partially filled tanks showed that liquid sloshing approximates to linear oscillation when external excitation is quite small. Besides, the modal analysis of liquid sloshing reveals that the first modal is the most important one to reflect the dynamics of liquid sloshing.…”

Tank vehicles have quite poor roll stability in driving. Therefore, the purpose of this article is to investigate tankers' roll stability by vehicle dynamic modeling. As a fluid-solid coupling multi-body system, tank vehicle's dynamic modeling must take liquid sloshing into account. The conventional solution on liquid sloshing by hydrodynamics is difficult and time-consuming, and the modeling of tankers obtained by this method was a distributed parameter system with infinite degree of freedoms. It was quite difficult and complicated to analyze tankers' dynamic features and to design active control system by the distributed parameter system. Therefore, three different methods to describe liquid sloshing effects in partially filled tanks with elliptical cross sections were proposed in this article, which are the estimation of liquid sloshing, the improved estimation of liquid sloshing, and the modeling of equivalent mechanical model for liquid sloshing. Then, the dynamic modeling of tank vehicles was commenced based on that. It was found out that the roll stability performance of tank vehicles obtained by different models differs with each other. The quasi-static model obtained by the estimation of liquid sloshing could get an estimation on tanker's rollover threshold quickly and easily, but it is with poor accuracy. The improved quasi-static model obtianed by the improved estimation of liquid sloshing could give a more accurate result on tanker's rollover threshold, the solution is also easily and quickly. Rollover analysis based on equivalent mechanical model of liquid sloshing could reflect vehicle's dynamics and is with high accuracy, but the process is of great complexity.

“…Among them, nonlinearity, linear theory, and simulation analysis of liquid sloshing were deeply studied. 1,2 In many fields, liquid sloshing brings a series of problems, such as driving instability, [3][4][5][6] sloshing noise, 7 structural damage, and evaporative emission. 8 Therefore, the effective control of liquid sloshing is a research direction that scholars pay close attention to at present.…”

Oil liquid sloshing is a normal physical phenomenon in fuel tank under variable conditions of vehicles. Installing baffles in fuel tank is an effective method to suppress oil liquid sloshing. The influence of different baffle shapes on the pressure of oil liquid sloshing and time-area value is the focus of this work. Four factors influencing the baffle shape and baffles of six different shapes are provided in this research. The pressure history curves of oil liquid sloshing at the central point and on the central line, the history curves of velocity of oil liquid mass and volume, oil liquid pressure contours, and the position diagrams of free oil liquid surface were obtained and compared in fuel tanks with baffles of different shapes. Compared with the sloshing pressure of oil liquid and time-area values in fuel tanks with baffles of different shapes, the sloshing pressure of oil liquid at the central point is the smallest in fuel tank with baffles of corrugated shape, and the sloshing pressure of oil liquid on the central line is the smallest in fuel tank with baffles of straight-line shape. However, the baffles of corrugated shape are most beneficial to reduce time-area values.
