Numerical Simulation of SloshingMitigating Structures in Tank Trucks With the SPH Method

  • 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.
