摘要

摘要: 基于光滑粒子动力学（SPH）方法对罐车的行驶稳定性、晃荡抑制措施进行了研究.首先模拟了矩形容器内的液体晃荡问题，仿真结果与试验结果吻合良好，表明SPH模型可以准确预测自由液面及容器壁面上的压力变化.之后，建立了二维椭圆形截面罐车模型，分析了装载93#汽油的罐车在水平正弦激励或横摇激励作用下，罐车壁面冲击压力和液体质心轨迹的变化情况.结果表明，无防晃结构时，车内液体晃动剧烈，结构的防晃效果会受外界激励形式的影响.防晃结构的法线方向与来流方向的夹角越小，则晃荡抑制效果越明显，重心越稳定.

Abstract: Based on the smooth particle hydrodynamics (SPH) method, the stability of the tank truck and the mitigating effects of different baffles were studied. Firstly, the liquid sloshing pressure in a rectangular container was simulated with results in agreement with experimental ones, to validate the effectiveness and accuracy of the SPH model. Secondly, a 2D elliptic tank truck model was established, which was filled with 93# gasoline. The impact pressure on the tank wall and the trajectory of the liquid barycenter were analyzed under different horizontal sinusoidal excitations and roll excitations. The results show that, the liquid sloshing is violent with no mitigating baffle, and the mitigating effects of the baffle will be influenced by the forms of external excitations. When the angle between the normal direction of the mitigating baffle and the inflow is small, the stability of the tank truck will be improved.
