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.
The VOF model was used to simulate the sloshing of the liquid during the steering of the tanker, and the single-chamber force and roll moment were calculated. The calculation results show that, with no anti-wave plate, with the increase of centripetal acceleration, vertical and horizontal The peak of force and the moment of roll become larger. With the increase of liquid topping ratio, the peak force in vertical direction increases, and the peak of peak force and roll moment in horizontal direction first increases and then decreases. With the anti-wave plate, Vertical and horizontal stress peak decreases. When the area of the wave-guard plate is greater than 30% of the longitudinal section area, the increase of the area of the wave-guard plate can significantly improve the force of the tank body. The peak value of roll moment firstly increases and then decreases. Wave plate area is equal to 30% of the longitudinal section to reach the maximum value, when the wave plate area is greater than 40% of the longitudinal section area of the wave plate can improve anti-shake effect.
