弹性膜对部分充液罐车内液体晃动的抑制效果研究OA北大核心CSTPCD

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.
