摘　　要：鉴于车辆油箱内矩形防浪板受到燃油的冲击后易发生断裂,设计了一种拱形防浪板,在保证油箱内燃油晃动减小的基础上防浪板力学性能大幅提高。通过Solid Works对油箱及内部防浪板进行三维建模,在尺寸相同的油箱中使用横截面积相同、材料相同的防浪板,利用ANSYS进行液晃、流固耦合、模态仿真。对比结果发现:2种防浪板都能达到减缓燃油晃动的效果,拱形防浪板具有更好的抗压性能。在相同材质和工艺条件下,将拱形防浪板取代矩形防浪板能达到更好的力学性能,从而避免断裂。Because the rectangular wave shield in vehicle oil tank is prone to fracture after being impacted by fuel oil,this paper designs a kind of arched wave shield,which can greatly improve the mechanical performance on the basis of reducing the rocking of fuel oil in the tank.SolidWorks software is used for three-dimensional modeling of the oil tank and the internal wave shield.Under the condition of using the same cross-sectional area and the same material of the wave shield in the oil tank with the same size,ANSYS software is used for liquid sway,fluid-structure coupling and modal simulation.The comparison results show that the both kinds of wave shields can reduce the fuel slosh,and the arched one has better compressive performance.Under the same material and process conditions,the arch wave shield instead of the rectangle one can achieve better mechanical properties,so as to avoid fracture.
