摘　　要：采用fluent软件VOF模型对罐车转向时的液体晃动进行了仿真,研究了罐式汽车转向行驶时侧向加速度、充液量、防波板对其行驶稳定性的影响。仿真结果表明与固体货物相比,液体货物随着侧向加速度、充液量的增加,横向力及侧倾力矩波动幅度增加迅速,使罐车行驶稳定性变差。因此降低侧向加速度、减少充液量、增设防波板可有效地提升罐式汽车的转向行驶稳定性。Using the fluent software VOF model ,liquid sloshing was simulated when tank vehicle is steer-ing.The influence of dashboard ,lateral acceleration and amount of liquid was analyzed on the driving sta-bility of tank vehicle when it is steering .The simulation results show that increase of lateral acceleration and amount of liquid , transverse force and roll torque fluctuation increases rapidly , compare with solid goods .It makes the driving stability of the tank vehicle worse .So it concluded that decreasing lateral ac-celeration ,reducing the quantity of liquid ,adding dashboard can effectively improve the driving stability of the tank vehicle on steering .
