Study on rollover risk of the tanker with different liquid filling coefficient in emergency turn

3D simulation model of petroleum sloshing in off-road tanker based on the VOF method, moving coordinate system and the actual size of the internal petroleum and tank structure is established in this paper. The mathematical model of the petroleum sloshing in tank is established, lateral rollover torque of petroleum sloshing in emergency turning is researched, the effects of the cross section shape and baffle area in tank on the dynamic characteristics of petroleum sloshing is studied.
