摘要
为了提高液罐车的制动性能和侧倾稳定性极限,建立了流固耦合模型,研究了弹性膜对部分充液罐车内液体晃荡的抑制效果.进行了实验室实验,实验结果验证了数值模型的有效性.验证后的模型被进一步用于研究不同的弹性膜配置对晃荡响应的影响,如液体载荷传递、晃荡力、俯仰力矩和罐壁压强.研究中考虑了两种不同的储罐配置,即没有任何阻尼装置的储罐和具有各种弹性膜组合的储罐,以进行比较.结果表明,添加弹性膜可以显著限制液体的运动,从而显著降低由晃动引起的俯仰力矩,这将提高罐车的制动性能和侧倾稳定性极限.
To improve the braking performance and roll stability limits of liquid tank vehicles,a numerical bi-directional fluid-structure coupling model was established to study the anti-slosh effects of elastic membranes on liquid sloshing in partially filled tank vehicles.Laboratory experiments were conducted to verify the validity of the numerical model.The validated model was further used to study the effects of various configurations of e-lastic membranes on sloshing responses,such as liquid load transfer,sloshing forces,pitch moments,and tank wall pressures.Two different tank configurations,namely tanks without membrane and tanks with various com-binations of elastic membranes,were considered in the study for comparison.The results show that,the addi-tion of membranes can significantly limit the movement of the liquid,resulting in dramatically reduced pitch moments caused by sloshing,which will improve the braking performance and roll stability limits of the tank vehicles.
