摘要: 采用VOF模型对罐车转向时液体晃动进行了数值模拟,对单室受力及侧倾力矩进行了计算.计算结果表明,无防波板时,随向心加速度增加,竖直、水平方向受力峰值及侧倾力矩均变大;随充液比增加,竖直方向受力峰值增大,水平方向受力峰值与侧倾力矩峰值先增大后减小;带防波板时,竖直、水平方向受力峰值减小,当防波板面积大于纵剖面积30%时防波板面积的增加能显著改善罐体受力;侧倾力矩峰值先增大后减小,在防波板面积等于纵剖面积30%时达到最大值,当防波板面积大于纵剖面积40%时防波板面积增加能提高防晃效果.Abstract: The liquid sloshing in turning process of tank truck was simulated by volume-of-fluid(VOF) model. The forces and turning moment of a single room were calculated. The results show that the maximum of Fy (force in direction y), Fz(force in direction z) and M (turning moment) increase when the centripetal acceleration increases without a baffle. When the liquid filling ratio increases, the maximum of Fy increases, the maximum of Fz and M increase firstly and decrease afterwards. When there is a baffle, as the area of the baffle becomes bigger, the maximum of Fy and Fz decrease and the maximum of M increases firstly and decreases afterwards.
