本文研究結果顯示，設置防波板對於抑制液體晃動效果明顯，防波板和隔板的改變對液體晃動的影響小於慣性力的變化，非等減速剎車對於罐體壁受力大小與反應時間的改變，比較與等減速剎車的差異。 Discussions on the free surface effects of tightly closed containers have wide application in engineering analysis and international focus research fields at all times which is complex and nonlinear. Filled tank vehicles relative to the low stability trucks carrying goods. Directional stability limits of partially filled liquid cargo tanks are significantly lower than those of conventional rigid cargo vehicles due to the unique dynamic interactions between the vehicle and the sloshing liquid cargo. The forces and moments arising from a directional maneuver yield considerable dynamic load shifts in the roll and pitch planes due to the sloshing of the liquid cargo within the partially filled tank. The dynamic load shift affects the directional stability of the partially filled tank trucks.
Supposing that the oil thank has enough rigidity and no elastic. The paper adopts the method of VOF to implement the numerical simulation of sharply liquid sloshing when the tank truck is in braking. it is studying on the dynamics and control of liquid sloshing in the tank truck. Simulation results show that models carrying with wave cutter or not, different baffles or wave cutter and non-deceleration brake change for analytic method about liquid.
The results show that the effect analysis of sloshing control with wave cutter is significantly obvious, the effect analysis of sloshing control with that different baffles or wave cutter is lower than apparent force changes, and the forces on the tank and response time change is different from between non-deceleration brake and deceleration brake.
