The sloshing free vibrations and the Equivalent Mechanical Model (EMM) parameters are determined for 2D multi-baffled containers under low-gravity conditions using Boundary Element Method (BEM) and potential flow model of the fluid. The presented model is applicable to any values of the acceleration of gravity and surface tension and to constant cross-section containers with arbitrary geometry, and baffle arrangement and shape. The results for a simple rectangular container are validated compared to the analytical values and very good agreement is achieved. Some baffled containers are also analyzed and their sloshing natural frequencies and EMM parameters are presented under low and zero-gravity conditions. Moreover, the effect of baffle characteristics on these parameters is investigated in a wide range of the acceleration of gravity and some conclusions are outlined.

使用边界元方法（BEM）和流体的潜在流动模型，确定了低重力条件下2D多挡板容器的晃荡自由振动和等效机械模型（EMM）参数。提出的模型适用于重力加速度和表面张力的任何值，以及具有任意几何形状，挡板布置和形状的恒定横截面的容器。与分析值相比，对一个简单的矩形容器的结果进行了验证，并获得了很好的一致性。还分析了一些有挡板的容器，并在低重力和零重力条件下显示了晃荡的固有频率和EMM参数。此外，
